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

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

The purpose of this study is to determine whether a wristband that detects your pulse can detect your heart rate and rhythm similar to electrocardiograms (ECG).

The purpose of this study is to determine whether a wristband that detects your pulse can detect your heart rate and rhythm similar to electrocardiograms (ECG). These wristbands detect your pulse based on a technique called "photoplethysmography," (PPG). PPG is a common method in which an individual's pulse is detected based on a light signature interpreted by the wristband. Most commercially available heart rate monitors use PPG to determine your heart rate, but the accuracy is variable.
