Measuring an individual’s heart rate appears to produce closely related results when the measurements are taken by an electrocardiogram or captured by photoplethysmography using a device such as a smartphone, according to a study published in npj Digital Medicine.

University of California San Francisco researchers recorded 10-second heart rate measurements from 50 participants after five minutes of rest. Heart rate was measured by PPG using a smartphone-based app as well as ECG. The researchers calculated the average differences between the two methods in milliseconds and beats per minute.

Using data from the 50 study participants, the research team performed a cross-sectional analysis of health information collected from 66,788 Health eHeart Study participants collected between April 2014-18. UCSF and the American...
