Figure Lengend Snippet: (A) Venn diagram depicting the primary mechanism of arrhythmia detection for select commercially available devices. Estimated retail price included. (B) Images of selective devices. (i) AliveCor Kardia Monitor device series . This device utilizes a single-lead ECG strip that can be mounted onto the back of a phone case or external card. Patients place one finger from each hand on to the two electrodes on the strip, and the devices records a single-lead ECG tracing. These devices have integrated algorithms that are able to detect the presence of AF based on the irregularity of the RR intervals and presence of a P-wave.

This device produces a six-lead ECG tracing by using a sensor on the back of the device that can be placed on the leg. It may be well suited for patients with atrial flutter, where flutter waves are better visualized in lead II. Picture source: https://store.alivecor.com/products/kardiamobile6l , (iii) Apple Watch. This series of wearable devices has been well studied for the detection of AF. Earlier iterations of the watch relied solely on PPG to detect heart rhythm irregularities, however the Series 4 and more recent iterations provide blended PPG and ECG capabilities. Picture source: https://www.apple.com/healthcare/apple-watch/ , (iv) Fitbit Sense . This wearable device uses PPG technology to detect heart rhythm abnormalities; there are additional apps available to provide ECG tracings. In this picture, we see that the Fitbit Sense describes the heart rhythm as AF, normal sinus or inconclusive.

Here, we see multiple screens showing the device’s prompt for the user to participate in an ECG measurement, a live tracing and an interpreted rhythm as sinus, respectively.
