Abstract :
The algorithm presented is based on the methods of percent of time above or below thresholds (PTABT), variability of threshold crossing intervals (TCI) and peak similarity in autocorrelation function (ACF). The algorithm offers a way to identify the ventricular fibrillation (VFib) and nonVFib rhythms with several features of electrocardiogram (ECG) rhythm and achieves a high sensitivity and specificity
