Table 5 The performance of the P wave detection algorithms on pathological signals from BUT PDB (Se—sensitivity, PP—positive predictivity, NaN—the whole signal is AFIB, no P waves are present, A—atrial premature beat, AFIB—atrial fibrillation, AFL—atrial flutter, B—ventricular bigeminy, BI—atrioventricular block 1st degree, BII—atrioventricular block 2nd degree, BIII—atrioventricular block 3rd degree, E—ventricular escape beat, F—fusion of ventricular and normal beat, IVR—idioventricular rhythm, J—nodal beat, L—left bundle branch block beat, NA—sinus arrhythmia, NOD—nodal rhythm, P—paced rhythm, PREX—pre-excitation, R—right bundle branch block beat, SVTA—supraventricular tachyarrhythmia, T—ventricular trigeminy, V—ventricular premature beat, VFL—ventricular flutter, VP—ventricular pair, a—aberrated atrial premature beat).
