After more than a decade on faculty at the University of California, San Diego, Sanjiv M. Narayan, MD, Ph.D. became a professor of medicine at Stanford University. A cardiologist, Dr. Sanjiv Narayan focuses on the diagnosis and treatment of atrial fibrillation.
Wearable and mobile devices may play a bigger role in the diagnosis of arrhythmias like atrial fibrillation. A recent study showed the efficacy of using smartphones to monitor for atrial fibrillation. The researchers used videoplethysmography software on smartphones that can use the selfie video function to identify irregular pulse rates. This sort of technology has become more important in recent months with telemedicine becoming more prevalent due to the coronavirus pandemic.
The video technology makes it possible to intermittently monitor for atrial fibrillation in a long-term fashion without the need for wearable devices. The software detects very subtle changes in skin color of the face during heartbeats to determine pulse rate. When compared to a standard ECG patch, the mean difference in pulse and heart rate between the technologies was only 0.3 beats per minute, indicating the efficacy of using smartphones as a contactless monitoring device.
