Abstract
Purpose of Review
This review describes the novel category of wearable ECG monitors and identifies where patients, healthcare providers, and device manufacturers should focus efforts to maximize the clinical benefit of these devices.
Recent Findings
Notable wearable ECG monitors include the AliveCor Kardia devices, Apple Watch Series 4, and several others. The most common use case is monitoring for atrial fibrillation. The available evidence validates the ability of the Kardia devices and Apple Watch to distinguish atrial fibrillation from sinus rhythm. Key questions for manufacturers include how to calibrate each device’s algorithms and streamline workflows for healthcare providers.
Summary
Wearable ECG monitors are currently most useful to detect atrial fibrillation. Further study is needed to demonstrate whether wearable ECG monitors improve patient outcomes, and to expand their use into other indications. Device manufacturers and healthcare providers must work together to establish new workflows to process and act on wearable ECG data.

The results suggest that wearable devices may be useful for long-term noninvasive monitoring for AF.

Assessment of remote heart rhythm sampling using the AliveCor heart monitor to screen for atrial fibrillation: The REHEARSE-AF Study. Circulation. 2017;136:1784–94 This randomized controlled trial compared screening with intermittent twice weekly handheld AliveCor Kardia ECGs for 12 months to usual care, and found that intermittent screening was more likely to detect incident AF in patients ≥ 65 years of age. It also estimated cost-effectiveness of such ambulatory screening, suggesting a cost per diagnosis of $10,780.
