Partial inhibition of ongoing antitachycardia pacing sequence due to T-wave oversensing.
We describe a case of partial inhibition of ongoing antitachycardia pacing scheme in an implantable cardioverter defibrillator (ICD) recipient with heart failure of ischemic etiology. The cause of inhibition was related to intermittent oversensing of paced T wave and sensing of intrinsic ventricular activation. In our effort to solve this problem, we reprogrammed the paced ventricular blanking period to a higher level.
