Accuracy of Rhythm Detection by a Wearable Smart Watch for Cardiac Arrhythmias (The WATCH-RHYTHM Study)

Accuracy of Rhythm Detection and Managing Data Deluge by a Wearable Smart Watch for Cardiac Arrhythmias (The WATCH-RHYTHM Study)

It is an attempt to see the reliability of the Wearable Smart Watch in identifying atrial fibrillation and other arrhythmias compared to the data detected from ILRs.

The sensitivity, specificity, positive and negative predictive values for successful identification of normal sinus rhythm, atrial fibrillation and other rhythm disorders from the smart watch will compared to that of an ILR.
