title: Inappropriate shock during left ventricular threshold measurement in a patient with coexisting ICD and a biventricular pacemaker.
abstract: Cardiac resynchronization therapy (CRT) using coronary sinus (CS) leads for biventricular stimulation is an established method for the therapy of congestive heart failure (CHF) in the case of inter- or intraventricular conduction delays. There are some patients having two separate devices: an ICD and a biventricular pacemaker. This case report describes an unusual interaction of these systems: an inappropriate VVI defibrillator shock during left ventricular threshold measurement in a biventricular pacemaker implanted on the other side.
