Introduction
Consumer-targeted wearable ECG devices hold the potential to facilitate earlier diagnoses and potentially improved outcomes through identification of coronary artery disease and cardiac arrhythmias.1 The first generation of these wearable devices has functionality primarily limited to diagnosing arrhythmic events, such as atrial fibrillation. Early research on the detection of atrial fibrillation with consumer wearable devices has shown that they are capable of reliable identification and characterization of arrhythmias.2
Most cardiovascular disease in developed nations is due to coronary artery disease (CAD), affecting over 15 million patients in the United States alone. The next generation of wearable devices aims to generate more extensive electrocardiographic projections to identify and potentially localize myocardial injury. The use of the right or left arm for precordial bipolar lead generation in a convenient wearable form factor may offer a viable solution for the detection of ischemic/infarction-related events.
