Smartphone electrocardiogram monitoring: current perspectives

Abstract:

Three-fourths of Americans now own smartphones. Mobile health applications are becoming increasingly common for the management of various chronic diseases, and have the potential to improve health outcomes. One of these is the sector of smartphone electrocardiogram (ECG) technology. Previously, obtaining an ECG has involved a bulky machine requiring medical training to operate. Most of the smartphone ECG technologies involve a single-lead ECG obtained on a small device that communicates with a smartphone. Many companies offer smartphone ECG technology. The most prevalent and studied of these is the Kardia Mobile device by AliveCor^®, which has a Food and Drug Administration-approved algorithm for detecting atrial fibrillation (AF). Here, we specifically review smartphone ECG technology including model specifications, cost, and ongoing clinical trials. We also review clinical uses of the technology including screening and monitoring of AF, QT monitoring during initiation of rhythm control medications, and the ability to accurately detect ST-elevation myocardial infarction.
