In a Brief Report in this issue of JAMA Cardiology by Spaccarotella and colleagues,1 the authors investigate the accuracy of using a direct-to-consumer smartwatch with single-channel electrocardiogram (ECG) capability to generate a multilead ECG for detection of ST-segment deviation. In 54 patients with ST-elevation myocardial infarction and 27 patients with non–ST-elevation myocardial infarction in a coronary care unit, the authors placed the watch in different body positions to obtain a full set of limb and precordial ECG leads. They compared ST-segment morphology classifications and amplitudes to a medical-grade, 12-lead ECG. Overall, there was good agreement in ST deviation and location.
