Key result
Sequential biventricular pacing using a triple chamber pacemaker was feasible in a patient with a previously implanted ICD, improving exercise tolerance and reducing NYHA class from III to II.
Why the study?
The feasibility and effects of sequential biventricular pacing in patients with end-stage heart failure and a previously implanted ICD were unclear.
Does a triple chamber pacemaker improve symptoms and ventricular resynchronization without adverse device interaction in a patient with end-stage heart failure and a previously implanted ICD?

Does a triple chamber pacemaker improve symptoms and ventricular resynchronization without adverse device interaction in a patient with end-stage heart failure and a previously implanted ICD?
Sequential biventricular pacing is feasible and can improve symptoms in end-stage heart failure patients with a previously implanted ICD without adverse device interactions.
A 63-year-old man with an ischemic dilated cardiomyopathy previously implanted with an implantable cardioverter defibrillator (ICD) received a triple chamber pacemaker as an ultimate therapeutic resort for end-stage congestive heart failure. After implant, the tolerance to physical exercise increased and NYHA class decreased from III to II. Echocardiography assessed ventricular contraction resynchronization during DDD biventricular pacing as compared to VVI pacing. No major pacemaker-ICD interaction was noted during testing or follow-up. We conclude that sequential biventricular pacing is feasible in the presence of an ICD.

Franc et al. (1998) conducted a case report in End-stage congestive heart failure (n=1). Triple chamber pacemaker (sequential biventricular pacing) vs. VVI pacing was evaluated on Feasibility, exercise tolerance, NYHA class, and pacemaker-ICD interaction. Sequential biventricular pacing using a triple chamber pacemaker was feasible in a patient with a previously implanted ICD, improving exercise tolerance and reducing NYHA class from III to II.
