Description of intervention(s) / exposure
A Holter monitor is a battery-operated portable device that records electrical heart activity continuously, often for 24 to 48 hours, to assist with the diagnosis, assessment and management of arrhythmias. Samsung has developed a Bio-Processor, a single, compact chip that is capable of measuring PPG, ECG skin temperature, GSR and body fat. This Bio-Processor is built into a device called the “S-Patch”, attachable to the chest with two electrode stickers; similar to a Holter monitor that attaches to the chest via five electrode stickers.

A low-risk, open-label, interventional study to compare data collected simultaneously from an S-Patch and Holter ambulatory ECG device in a community setting. Patients will be fitted with both the S-Patch and a Holter monitor for 24 hours, filling out a questionnaire to compare the experience of using both devices. The data collected is immediately loaded into the cloud to confirm evaluability and will be later analysed by the clinical team to establish accuracy and efficacy. Any relevant clinical findings will be reported to the patient's medical team, using the holter data only.
The clinical team will also complete a questionnaire comparing the experience of using both devices. A report will be generated with recommendations made for any changes required to the software and/or hardware.

The trial has been staged in 3 parts:
Part 1: Pilot Simultaneous S-Patch and Holter Monitor Comparison (beta testing phase), looking at 25 patients where the S-patch analysis software is updated during the evalaution.
Part 1a: Pilot Simultaneous S-Patch and Holter Monitor Comparison (confirmation of beta -testing completion phase), looking at 5 patients after further refinement of the S-patch device.
Part 2: Simultaneous S-Patch and Holter Monitor Comparison (proof of concept), looking at 60 patients using a static "final" S-patch device and analytical software,

Outcomes
Primary outcome [1] 304126 0
Quality of data generated by both devices - analysis performed by cardiologists.
Raw data from the S-Patch device will be directly compared to raw data from the traditional Holter monitor, over 24 hours for ambulatory ECG readings.

A Cardiac Physiologist will assess
• Cardiac rhythm (sinus rhythm, atrial fibrillation, atrial flutter, junctional rhythm)
• Minimum, maximum and average heart rate
• Burden of atrial fibrillation and atrial flutter, junctional rhythm
• Premature Ventricular Contraction (PVC) burden
• Presence of the following (number, fastest rate, longest duration)
-Ventricular tachycardia
-Supraventricular tachycardia
• Alert events
-Heart rate >180/min or <40/min
-Pauses >3 seconds

Statistical methods / analysis
A Cardiac Physiologist will review the data and detail the Standard of Care findings report and the following additional information.
• Cardiac rhythm (sinus rhythm, atrial fibrillation, atrial flutter, junctional rhythm)
• Minimum, maximum and average heart rate
• Burden of atrial fibrillation and atrial flutter, junctional rhythm
• Premature Ventricular Contraction (PVC) burden
• Presence of the following (number, fastest rate, longest duration)
o Ventricular tachycardia
o Supraventricular tachycardia
• Alert events
o Heart rate >180/min or <40/min
o Pauses >3 seconds

Holter monitor data will be read by a number of different Cardiac Physiologists within the department, and a standard report generated. To minimise the impact of the learning curve when reading the S-Patch data, one dedicated Cardiac Physiologist will read and report on all of the S-Patch data.
Primary outcomes from the evaluation (Investigator) will be used to report incremental cost-effectiveness ratios (ICER). The ICER will be expressed by the difference in costs divided by the difference in effects, and presented as cost ($) per effect with 95% confidence intervals. Probabilistic sensitivity analysis will be performed to test the robustness of the results across a range of possible values.
