Objective: We have developed a peak detection algorithm for accurate determination of heart rate, using photoplethysmographic (PPG) signals from a smartwatch, even in the presence of various cardiac rhythms, including normal sinus rhythm (NSR), premature atrial contraction (PAC), premature ventricle...
Some limitations should be acknowledged. Participants did not report a specific medication-free period for any heart arrhythmia to reduce recall bias and increase their convenience. A single-lead rhythm ECG with 6 min recording time was used in this pilot investigation for feasibility. A longer ECG...
A single-lead rhythm ECG with 6 min recording time was used in this pilot investigation for feasibility. A longer ECG rhythm recording duration might have improved RSA and ectopic arrythmia detections. Factors such as breathing patterns and ranges were not controlled during ECG assessments, although...
