May support AV optimization in select DDD-paced HF cases; leaves open confirmation in prospective trials.
Does DDD pacemaker implantation with AV delay optimization improve cardiac function and prevent hospitalizations in a patient with congestive heart failure, prolonged PQ interval, and left bundle branch block?
DDD pacing with optimal AV delay determined by Doppler echocardiography can effectively control severe congestive heart failure in patients with a prolonged PQ interval and left bundle branch block.
Ishikawa et al. (2001) studied this question.
