Probability of ventricular arrhythmias following stereotyped short-long sequences: a computerized analysis of digitized dynamic ECG recordings

Stereotyped “short-long” templates have been described to precede the spontaneous onset of ventricular arrhythmias. Individual “short-long” cycle length sequences can be modelized and implemented to digitized Holter recordings, in order to detect how often a specific template is followed by ventricular arrhythmias. Thus, the probability of individual “short-long” templates to be followed by ventricular arrhythmias can be computed. Therefore, the quantitative scanning of digitized Holter recordings for individual-specific cycle length sequences can be viewed as new “non-invasive electrophysiologic test” exploring the individual cycle length determinants of ventricular arrhythmias
