Implantable devices capable of several modes of therapy will require differentiation of
various ventricular tachyarrhythmias. Three methods of arrhythmia analysis, magnitude …

Three methods of electrogram analysis have been investigated: rate, irregularity, and
amplitude distribution. In 35 episodes in 19 patients, these three algorithms were applied to …

Implantable antitachycardia devices suffer a high false‐positive rate of delivery of therapy
because current detection schemes based upon ventricular rate and rate variations are …

Currently available antitachycardia devices rely primarily on timing information to define
abnormal rhythms. It would be useful to have more specific means of automatically …

Results are reported of analysis of the variability of complex ventricular arrhythmias in a
cohort of 110 patients selected for the presence of ventricular tachycardia (VT). All patients …

Implantable antitachycardia devices are now capable of providing “ramp” therapy including
antitachycardia pacing and low-and high-energy cardioversion for sustained ventricular …

A great deal of new information has emerged concerning the mechanisms,
electrocardiographic (ECG) recognition, electrophysiological behavior, and management of …

Current automatic implantable cardioverter-defibrillators detect tachyarrhythmias primarily
by rate-only algorithms and cannot adequately distinguish hemodynamically stable from …

Objectives. This study was designed to analyze stored intracardiac electrograms generated
during spontaneous monomorphic ventricular tachycardia to examine the possible …

The authors have designed four new computationally efficient time-domain algorithms for
distinguishing ventricular electrograms during monomorphic ventricular tachycardia (VT) …
