Consumer wearable devices with ECG capabilities, such as the Apple Watch, can be useful in detecting and diagnosing previously unidentified paroxysmal atrial fibrillation.
May support consumer ECG for symptomatic arrhythmia detection; hypothesis-generating, requires prospective validation before practice change.
Consumer rhythm-monitoring devices, such as the Apple Watch, are becoming more readily available. Irregular pulses can be detected using an optical sensor built into the wearable device. The Apple Watch (Apple Inc., Cupertino, CA, USA) is a class II medical device with pulse rate and electrocardiography (ECG) monitoring capabilities. Here we report a case in which an arrhythmia that was conventionally perceived but undiagnosed was identified as atrial fibrillation by self-acquisition of ECG data using an Apple Watch.
