Detection of atrial fibrillation with a smartphone camera: first prospective, international, two-centre, clinical validation study (DETECT AF PRO)

Figure 1. Index and middle fingers on a mobile iECG (left panel); excerpts from resulting iECGs (right panel): (A) SR, (B) SR with ectopic beats, and (C) AF (right panel). AF, atrial fibrillation; iECG, internet-enabled electrocardiography; SR, sinus rhythm.

Figure 2. PPG recording with a smartphone camera on the index finger (left panel); excerpts from resulting pulse waves (right panel): grey wave form indicates the pulse wave, black projected spikes indicate a regular heartbeat (A). Yellow spikes indicate an irregular heartbeat (e.g. ectopic beat) (B), red spikes an extremely irregular heart rhythm (absolut arrhythmia) (C). PPG, photoplethysmography.
