Why the study?
Does a low-power wearable ECG monitoring system provide comparable QRS sensitivity and positive predictability to a commercial clinical ECG recorder in healthy adults?
Does a low-power wearable ECG monitoring system provide comparable QRS sensitivity and positive predictability to a commercial clinical ECG recorder in healthy adults?
A novel low-power wearable ECG monitoring system was developed and tested against a commercial clinical ECG recorder for QRS detection accuracy in healthy adults.
May enable ambulatory ECG monitoring; leaves open validation in patients with arrhythmias before clinical adoption.
A low-power wearable ECG monitoring system has been developed entirely from discrete electronic components and a custom PCB. This device removes all loose wires from the system and minimizes the footprint on the user. The monitor consists of five electrodes, which allow a cardiologist to choose from a variety of possible projections. Clinical tests to compare our wearable monitor with a commercial clinical ECG recorder are conducted on ten healthy adults under different ambulatory conditions, with nine of the datasets used for analysis. Data from both monitors were synchronized and annotated with PhysioNet's waveform viewer WAVE (physionet.org) [1]. All gold standard annotations are compared to the results of the WQRS detection algorithm [2] provided by PhysioNet. QRS sensitivity and QRS positive predictability are extracted from both monitors to validate the wearable monitor.
