Abstract
In one example, a cardiac monitoring system, comprises a processor to receive a segment of an electrocardiogram (ECG) signal of a patient, and a memory to store the segment of the ECG. The processor is configured to identify QRS complexes in the segment of the ECG signal, compare the QRS complexes in the segment to the other QRS complexes in the segment to identify a main template QRS complex, identify the QRS complexes in the segment that are similar to the main template, determine RR intervals between consecutive similar QRS complexes to calculate RR variability in the RR intervals, and detect atrial fibrillation (AF) in the segment when RR variability is greater than a threshold value. Other examples and related methods are also disclosed herein.
