Continuous Data Collection and Analysis for Stroke Prevention Using a Wearable Sensor

Subjects will be asked to wear a wrist band with capabilities to detect their heart rate or rhythm on the basis of PPG on either wrist around the time of their cardioversion procedure. Data will be acquired from the wrist band at the same time as the electrocardiogram (ECG) monitor to which subjects are hooked up for the purposes of the cardioversion.

Subjects will be sent home after the cardioversion with a 30 day heart monitor called the BodyGuardian. This device continuously monitors their heart rate and rhythm and they will wear this on the chest. Subjects will also wear the wrist monitor over the same 30 day period.
