Retraction Of PublicationRetracted: Considerations in patients undergoing implantation of a biventricular pacemaker.
To compare hemodynamics and oxygenation in patients with congestive heart failure and broad QRS complexes before and with biventricular DDD pacing and to report experience with this new procedure. ⋯ There was no acute intraoperative improvement of hemodynamics except increased mean arterial pressure with biventricular pacing. Left ventricular performance seemed to improve with biventricular pacing in some patients. These results might be due to a nonoptimized atrioventricular delay. Postoperatively, atrioventricular delay was individually programmed for each patient by Doppler transmitral flow patterns.
