A New Defibrillator Discrimination Algorithm Utilizing Electrogram Morphology Analysis

Abstract: Inappropriate therapies delivered by implantable cardioverter defibrillators (ICDs) for supraventricular arrhythmias remain a common problem, particularly in the event of rapidly conducted atrial fibrillation or marked sinus tachycardia. The ability to differentiate between ventricular tachycardia and supraventricular arrhythmias is the major goal of discrimination algorithms. Therefore, we developed a new algorithm, SimDis, utilizing morphological features of the shocking electrograms. This algorithm was deve… Show more

“…Finally, inappropriate ICD discharges in the event of supra-ventricular tachyarrhythmias are a well-recognised risk [21][22][23][24][25] , which have been described to induce lifethreatening ventricular tachyarrhythmias in some individuals. [26][27][28] In the present study, however, only one inappropriate ICD shock without pro-arrhythmic effect was delivered to a patient in sinus tachycardia during exercise training and none in between sessions.…”

“…Perhaps more important, improvements in atrial sensing and morphology-based algorithms, which may substantially improve dual-chamber detection, have recently become available. [12][13][14][15] We hypothesized that the optimal use of the latest generation dual-chamber detection enhancements would decrease inappropriate detection of SVT compared with optimal single-chamber detection enhancements in a broad population of ICD recipients. If true, this would indicate that dualchamber ICDs are preferable to single-chamber devices in most ICD recipients because of a decrease in the morbidity due to inappropriate therapy.…”

“…In single-chamber devices, there are three discriminators. [71][72][73][74][75][76][77][78] Firstly, onset, which is usually sudden with rapid acceleration in VT as opposed to the gradual increase in heart rate in sinus tachycardia. Secondly, heart rate stability, which helps to discriminate between AF and VT.…”
