Comparison of 7-Day ECG Patches

June 22, 2026 updated by: Medical University Innsbruck

Comparison of Commercially Available 7-Day ECG Patches: A Randomized Study

This prospective, randomized, multi-arm study evaluates the usability and performance of commercially available CE-certified 7-day ECG patches in an outpatient setting. Participants aged ≥65 years requiring ECG monitoring as part of routine care will be randomized to one of six ECG patch devices. The study aims to assess the proportion of analyzable ECG recordings and overall recording quality over a 7-day period.

Detailed Description

Atrial fibrillation is a common arrhythmia often underdiagnosed due to its intermittent nature. Long-term ECG monitoring using wearable patch devices has emerged as an important diagnostic tool. However, comparative data between available devices are lacking.

This randomized study compares six commercially available ECG patches regarding usability, adherence, and recording quality in an elderly outpatient population. Participants will independently apply the assigned device and undergo 7-day ECG monitoring. Device performance and patient feedback will be systematically assessed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of participants with analyzable ECG recording ≥24 hours
Time Frame: 7 days
The proportion of participants who achieve at least 24 hours of analyzable ECG recording during the 7-day monitoring period. Analyzable ECG recording is defined as ECG data of sufficient technical quality to allow rhythm assessment, as determined by the certified analysis algorithm provided by the device manufacturer. Periods with insufficient signal quality (e.g., due to noise, signal loss, or artifacts) are excluded.
7 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cumulative analysable ECG time
Time Frame: 7 days
Cumulative duration, in hours, of analysable ECG obtained per participant during the intended 7-day monitoring period, where analysable ECG is defined as ECG of sufficient quality, according to the manufacturer's signal-quality criteria, to permit rhythm analysis. Participants without any recording were assigned a value of 0 hours.
