The FDA-cleared ZIO Patch is a small, adhesive, water-resistant one lead ECG sensor that the user can stick onto their chest for a continuous 24-hour monitoring over 2 weeks. 2020-9-3 The Zio Patch monitor is applied using a small adhesive bandage - approximately two by five inches - to the patient’s chest. The adhesive bandage holds the monitor in place where it monitors heart rhythms on a continuous basis. Patients are able to continue normal activities such as exercise and showering while wearing the Zio Patch.
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity, generally by electrocardiography, with assessment of the patient's condition relative to their cardiac rhythm. It is different from hemodynamic monitoring, which monitors the pressure and flow of blood within the cardiovascular system. The two may be performed simultaneously on critical heart patients. Cardiac monitoring with a small device worn by an ambulatory patient (one well enough to walk around) is known as ambulatory electrocardiography (such as with a Holter monitor, wireless ambulatory ECG, or an implantable loop recorder). Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry.
Cardiac monitoring in the ED setting has a primary focus on the monitoring of arrhythmia, myocardial infarction, and QT-interval monitoring. It is a noninvasive diagnostic tool and monitoring is categorized by the rating system developed by the American College of Cardiology Emergency Cardiac Care Committee.
- EPatch is a lightweight cardiac monitor that adheres to the patient’s chest. And unlike other patches, if ePatch loses adhesion it may be replaced by a fresh patch (or small electrode adaptor for sensitive skin) without terminating the recording session.
- Now available at Spire St Anthony's Hospital, the new ZIO® XT Patch is a continuously recording, wire-free heart monitor that can be worn for up to 14 days.
- The technology behind the Zio Patch is able to filter between what it detects as the heart’s rhythm and what may be interference. When compared to other wearable cardiac monitors, the Zio Patch is favored for its ease of use for patients and its accuracy for diagnosing cardiac events for physicians.
The different classes are as follows: Song pk video songs download.
Class I: Cardiac monitoring is indicated in all or most patients.
Class II: Cardiac monitoring may be beneficial, but it is not essential.
Class III: Cardiac monitoring is not indicated because the patient's serious event risk is low. Monitoring will not have therapeutic benefit.[1]
Emergency medical services[edit]
In the setting of out-of-hospital acute medical care, ambulance services and other emergency medical services providers utilize heart monitors to assess the patient's cardiac rhythm. Providers licensed or certified at the Paramedic level are qualified to interpret ECGs. Information obtained from ECGs can then be used to direct the patient's treatment at a care facility, particularly in catheterization labs.[2]
In the emergency department[edit]
In the emergency department, cardiac monitoring is a part of the monitoring of vital signs in emergency medicine, and generally includes electrocardiography.
Monitor/Defibrillators[edit]
Some digital patient monitors, especially those used EMS services, often incorporate a defibrillator into the patient monitor itself. These monitor/defibrillators usually have the normal capabilities of an ICU monitor, but have manual (and usually semi-automatic AED) defibrillation capability. This is particularly good for EMS services, who need a compact, easy to use monitor and defibrillator, as well as for patient transport. Most monitor defibrillators also have transcutaneous pacing capability via large AED like adhesive pads (which often can be used for monitoring, defibrillation and pacing) that are applied to the patient in an anterior-posterior configuration. The monitor defibrillator units often have specialized monitoring parameters such as waveform capnography, invasive BP, and in some monitors, Masimo Rainbow SET pulse oximetry.Examples of monitor defibrillators are the Lifepak 12, 15 and 20 made by Physio Control, the Philips Heartstart MRx, and the E, R, and X Series by ZOLL Medical.

Long-term ambulatory monitors[edit]
There are two broad classifications for cardiac event monitors: manual (or dumb) and automatic. Automatic ECG event monitors have the ability to monitor the patient's ECG and make recordings of abnormal events without requiring patient intervention. Manual ECG event recorders require the patient to be symptomatic and to activate the device to record an event; this makes these devices useless whilst, for example, the patient is sleeping. A third classification, the implantable loop recorder, provides both automatic and manual abilities.
An example of automatic monitoring is the transtelephonic cardiac event monitor. This monitor contacts ECG technicians, via telephone, on a regular basis, transmitting ECG rhythms for ongoing monitoring. The transtelephonic cardiac event monitor can normally store approximately five 'cardiac events' usually lasting 30–60 seconds.

Heart rate monitoring[edit]
Monitoring of the heart rate can be performed as part of electrocardiography, but it can also be measured conveniently with specific heart rate monitors. Such heart rate monitors are largely used by performers of various types of physical exercise.
A generic cardiac monitor has the following functions:
- A display of heart rate and heart rhythm
- Sound alarms above and below a pre-set limit
- Ability to determine the presence of arrhythmia
There are many different types of cardiac monitors. In personal use, the Holter monitor is an external monitor which uses wires with patches that attach to the skin to continuously measure and record heart activity for 1–2 days.[3] An Event Recorder can be worn on the body for up to 30 days.[4] A Mobile Cardiac Telemetry unit is a wearable monitor that detects, records, and transmits heart rhythms for up to 30 days. For long term use, an Insertable Cardiac Monitor is placed under the skin and automatically detects and records abnormal heart rhythms for up to 5 years.[5]
Fetal Heart Rate Monitoring
Monitoring the fetal heart rate is becoming increasingly prevalent in the standard care of antepartum pregnant patients.[6] As of 2002, 85% of pregnancies in the United States were monitored using electronic fetal monitoring. Electronic fetal monitoring uses Doppler ultrasound technology to provide real-time feedback on the fetus’s cardiac activity during both gestation and labour.[7]
Wearable Heart Rate Monitors for Exercise[edit]
The new wearable heart rate monitors indirectly measure the heart rate with reflectance photoplethysmography. The monitor illuminates the skin tissue with light emitting diode (LED) and detects the intensity of light reflected with the photodetector.[8] Wearable optical heart rate monitors are less reliable than electrode-based heart rate monitors. The accuracy of the wearable optical heart rate monitors varies with the type of exercise. Skin tone and motion artifacts contributes to this error.[8][9]
Insurance Coverage[edit]
There are two types of cardiac monitoring that is covered by Medicare:
- Ambulatory electrocardiography (AECG): includes cardiac monitoring that is situated in an outpatient setting during a specific period. A ECG devices are different from other cardiac monitoring tools as they can be used to determine specific incidences of arrhythmia, which is not typically detected using a standard ECG. Therefore, the A ECG devices are typically used to identify and determine the severity of symptoms associated with cardiac arrhythmia's and/or myocardial ischemia. A ECG devices are typically conducted by independent diagnostic testing facilities (IDTFs).
- Transtelephonic monitoring of cardiac pacemakers (CPT code 93293): monitoring of cardiac pacemakers are necessary to ensure the quality and condition of pacemakers and identify any potential drawbacks or signs of pacemaker failure, which reduces the possibility of sudden pacemaker failures[10]

The technology
The technology
The Zio Service (iRhythm Technologies) is designed to detect cardiac arrhythmias and is comprised of the Zio Patch, an adhesive patch with a 1‑lead ambulatory electrocardiogram (ECG), and the Zio Report, a summary of the recorded data that have been analysed.
The Zio Patch is a lightweight water-resistant ECG monitor that has no external leads or wires. The patch is stuck on the person's left upper chest and can record a continuous beat-to-beat ECG for up to 14 days. Each Zio Patch is intended for single-patient use.
Wearers can carry on with their usual daily activities during monitoring. When they feel a symptom, the wearer can press a trigger button on the device that highlights the recording 45 seconds before and after the button was pressed. The wearer is also asked to keep a paper-based log in which they write down any symptomatic events that happen during the 14‑day monitoring period, as well as information on what they were doing and the conditions at the time. This allows for a symptom-rhythm correlation to be included in the final report.
After the monitoring period, the wearer removes the Zio Patch and sends it to the company by Freepost through the Royal Mail. The recordings are analysed by the company, using proprietary machine-learned algorithms (Zio ECG Utilization Service System [ZEUS System]), and a report is produced. The report describes all cardiac arrhythmia events over the total wear time and the analysis by the ZEUS system, and it is reviewed by a certified cardiac technician. This Zio Report is sent electronically to the ordering clinician through iRhythm's secure web-based portal. The full ECG data can be sent to the clinician on request. Patient data are otherwise only used by the company in a de‑identified form for quality reporting and system improvements.
Parts of the analysis are done in the UK and the US. The manufacturer states that transmission, processing and storage of all data complies with relevant EU and UK legislation. There are no patient identifiers in or on the Zio Patch and data cannot be accessed if the Zio Patch were to be physically intercepted. iRhythm uses security measures to prevent inappropriate access to or manipulation of the data.
Innovations
The Zio Service provides a continuous recording of ambulatory cardiac monitoring for up to 14 days. The wearer can go about their normal daily activities during monitoring, including showering or bathing because the device is water resistant.
The Zio Service can be used for a longer monitoring period than a standard Holter monitor, which can be up to 7 days but usually for 24 to 48 hours. The Zio Patch has no external leads or wires and this is intended to reduce noise artefacts in the data. It can be worn under clothing, so may be more discreet than Holter monitors, which are generally worn in a pouch around the waist or neck, or carried in a pocket.
Zio Patch Instructions For Use
The Zio Service uses machine-learned analytics in the form of proprietary software to create the report that is delivered to the clinician. This is intended to reduce the time needed for NHS staff to analyse the continuous monitoring data.
Current NHS pathway
The current methods of arrhythmia detection (NHS Choices) are:
- 12‑lead ECG
- 24- to 48‑hour or 7‑day continuous ambulatory monitoring, including using Holter monitors
- long-term continuous monitoring for up to 30 days
- external loop recorders
- insertable loop recorders, which can record events for up to 3 years for arrhythmias that occur sometimes months apart.
The Holter monitor is the method most commonly used in the NHS for detecting atrial fibrillation. Holter monitors continuously record the heart rhythm using several electrode patches, which are stuck on the user's chest. These electrodes detect and record electrical signals produced by each heartbeat, and are connected by wires to a portable recording machine. The user can press a button on the front of the recording machine at specific times, such as when having symptoms, going to bed or taking medication. These points can then be easily found in the continuous monitoring data. Holter monitoring is used for 24 to 48 hours for people who have regular symptoms, or can be used for up to 7 days for people with symptoms that happen less often, such as if they only have arrhythmia every 3 to 4 days. Results are analysed by the user's clinician.
Free raul di blasio disco grafia rares. The NICE guidelines on managing atrial fibrillation and transient loss of consciousness ('blackouts') in over 16s recommend a 12‑lead ECG for the first assessment. If further assessment of possible cardiac arrhythmia is needed, ambulatory ECG monitoring is recommended for 24 or 48 hours. The choice of monitor depends on symptoms and symptom frequency and includes Holter monitoring and external or implantable event recorders.
If the first 24- to 48‑hour Holter monitor test does not give a clear diagnosis, people are referred for further investigations. This can include event recording for up to 7 days or admission to hospital for more invasive options, such as fitting an implantable loop recorder.
Estimates of the diagnostic yield for 24‑hour Holter monitoring vary. Barbeito–Caamano et al. (2016) reported that syncope was only diagnosed in 4% of people in a cohort monitored for 24 hours. De Asmundis et al. (2014) reported that Holter monitoring led to a diagnosis of any arrhythmia in 1.8% of people monitored for 24 hours, whereas Kinlay et al. (1996) reported a diagnosis rate of 35% after 48‑hour Holter monitoring.
The Zio Service would be used for monitoring over 14 days as well as, or instead of, 24- to 48‑hour and 7‑day Holter monitoring or event recording.
NICE is aware of the following CE‑marked devices that appear to fulfil a similar function to Zio Service:
- Bardy 7‑day patch (Cardiologic)
- SEEQ MCT monitor (Medtronic)
Population, setting and intended user
The Zio Service would be used in a home setting for people with suspected cardiac arrhythmias. The device can be used for people with suspected arrhythmias and unexplained loss of consciousness. The Zio Service would be used instead of Holter monitoring or event recording when continuous monitoring needs to be extended for up to 14 days.
A clinician would prescribe monitoring with the Zio Service, most likely a cardiologist in secondary care or possibly a GP in primary care. The Zio Patch is intended to be applied to the person by the clinician, or by a cardiac physiologist or healthcare support worker in hospital, or a nurse or healthcare support worker in primary care. Occasionally, it may be applied by the person themselves if the clinician thinks that this is appropriate. After the monitoring period, the person sends the Zio Patch by Freepost through the Royal Mail to iRhythm for data analysis and production of the report.
The manufacturer states that minimal training is needed to apply and use the Zio Patch and that full instructions are provided in the user manual. The chest area may sometimes need to be shaved before applying the device. iRhythm states that the clinician will not need additional training to interpret the Zio Report, because it is clear and complete.
Very occasionally, such as with paroxysmal atrial fibrillation, monitoring for more than 14 days may be needed because events are very intermittent. In this situation 2 patches would be worn in succession.
Costs
The manufacturer has given an example list price of £800 per unit for the Zio Service. In practice, prices will vary depending on the procurement and volume arrangements for each hospital. This single price includes the cost of the Zio Patch, the data analysis, and the clinical report for one 14‑day monitoring period for a single patient. A specialist commentator provided the following costs (excluding equipment costs) for 24‑hour Holter monitoring, per patient:

- monitoring and interpretation of results:
- £95.42 without overheads (defined as staff, heating and computer use)
- £118.60 with overheads
- monitoring and no interpretation of results:

An example of a reusable Holter monitor is the Spacelabs LifeCard CF Holter recorder, which has a list price of £1,632.14 (NHS Supply Chain).
Zio Patch Cardiac Monitoring Cost
Resource consequences
Zio Patch Cardiac Monitoring Center
The Zio Service is currently available in 6 NHS trusts.
The purchase price of the Zio Service may be lower than that of a Holter monitor, but the cost of 24‑hour Holter monitoring per patient would be lower. Cost savings could be generated if using the Zio Service reduced the need for repeated or prolonged Holter or event monitoring. The Zio Service offers 14‑day monitoring, which may improve the detection of infrequent arrhythmias compared with 24- to 48‑hour or 7‑day Holter monitoring. This could save any costs that could be avoided by having a correct diagnosis, including repeat hospital inpatient and outpatient admissions related to complications such as syncope, chest pain, stroke or transient ischaemic attack.
Zio Patch Cardiac Monitoring Device
The costs of applying the Zio Patch to the patient are minimal. It is simple to use and can be removed without medical supervision. People having Holter monitoring must visit the cardiologist to return the monitor after the recording period, whereas the Zio Service is returned to iRhythm by post, which may be more convenient for people.
