Abstract

Congestive heart failure (CHF) patients with LBBB and QRS duration >150 ms are considered the best candidates to biventricular pacing (Biv-P). However, patients with a narrow (120-150 ms) QRS may also benefit from Biv-P since true ventricular dyssynchrony may be underestimated by considering only QRS enlargement. From October 1999 to April 2002, 158 CHF patients (121 men, mean age 65 years, mean LVEF 0.29, mean QRS width 174 ms) underwent successful Biv-P implantation and were then followed for a mean time of 11.2 months. According to basal QRS duration, patients were divided in two groups, with wide QRS (≥150 ms, 128 patients, 81%) and with narrow QRS (
