Does programming the sinus redetection parameter to slow correct undersensing during ventricular tachyarrhythmias in patients with Ventritex Cadence defibrillators?
Undersensing during ventricular tachyarrhythmias in third-generation ICDs can lead to therapy failure, but can be diagnosed via stored electrograms and corrected by adjusting sinus redetection programming.
Mann et al. (1994) studied this question.
