Right ventricular lead ring capture in sequential biventricular pacing with pseudo-bipolar left ventricular lead configuration: an unwanted effect.
نویسندگان
چکیده
We report here on three patients who underwent biventricular pacing (BVP) for severe heart failure and the problems encountered with pseudo-bipolar left ventricular (LV) lead configuration. With this configuration, right ventricular anode capture with simultaneous biventricular stimulation was noted at higher output during the isolated LV pacing mode in these patients, which forced us to program the LV pacing to unipolar configuration in one patient. The implication of this phenomenon in sequential BVP therapy is discussed.

BACKGROUND Phrenic nerve stimulation (PNS) and high pacing thresholds (HPT) hinder biventricular stimulation in patients (pts) undergoing cardiac resynchronization therapy (CRT). A new quadripolar left ventricular (LV) lead (Quartet 1458Q, St. Jude Medical) with increased number of pacing configuration, might overcome this problem. METHODS All consecutive pts in whom a standard bipolar lead i...

In recent years, cardiac resynchronization therapy or biventricular pacing has been proved to be effective in alleviating congestive heart failure in 70% of patients. For patients who have bradycardia devices in place before presentation of heart failure and the devices are well before end of life, the RV pacing system can be effectively, efficiently and safely upgraded to bi-ventricular pacing...
متن کاملTemporary left ventricular pacing improves haemodynamic performance in patients requiring epicardial pacing post cardiac surgery.
OBJECTIVE In the 1990s, sequential atrio-ventricular pacing demonstrated haemodynamic benefit relative to right ventricular pacing in patients with sinus rhythm requiring pacing post cardiopulmonary bypass. The benefit of biventricular pacing has been demonstrated in non-surgical patients with severe left ventricular dysfunction. It was hypothesised that left ventricular pacing would increase c...
متن کاملA comparison of cardiac resynchronization by sequential biventricular pacing and left ventricular pacing to simultaneous biventricular pacing: rationale and design of the DECREASE-HF clinical trial.
BACKGROUND The first generation of cardiac resynchronization therapy (CRT) devices approved for the treatment of heart failure used simultaneous biventricular (BiV) pacing to achieve ventricular resynchronization. Left ventricular pacing alone and sequential BiV pacing also show promise as alternative ways to deliver CRT, but have not been studied together in a large randomized trial. METHODS...
