With the increasing use of direct-to-consumer medical devices, it is paramount for clinicians to recognize the potential utilization for patient management. The increasing adoption of this new class of consumer-grade wearable devices that monitor heart rate and activity as well as smartphone technology that integrates information from devices (blood pressure monitors, digital scales, pedometers) can prove useful in the diagnosis and management of some patients. Devices and applications that are specifically designed to measure heart rate and electrocardiographic signals are particularly useful for determining if an arrhythmia is present (such as atrial fibrillation, paroxysmal supraventricular tachycardia, or ectopic beats). An example of this appears in Figure 1.
