Analysis of atrial tachyarrhythmias requires that an atrial signal has first been extracted from the electrocardiogram (ECG), resulting in the so-called residual ECG. This article introduces a novel method for atrial rhythm analysis that condenses different signal parameters into three rhythm features, reflecting signal structure, frequency regularity, and waveform type. A three-stage method for atrial signal analysis is introduced and comprises atrial signal extraction, atrial signal characterization, and atrial rhythm feature analysis. The present study is example based and illustrates the potential of the method. A quantitative evaluation of the performance of the method will be done in a future study
