From 2001 to 2006, 93 patients with heart failure in NYHA functional class III or IV of any etiology, associated to a left bundle-branch block with QRS [greater than or equal to] 120 ms, clinically treated with optimal medical therapy at the Pacing and Arrhythmia Unit of InCor-HCFMUSP, were retrospectively investigated.
Cardiac pacing devices, among which the multi-site (atrial-biventricular) pacemakers, have already been used with the purpose of promoting better homogeneity of electrical activation of the myocardium, and therefore, of the segmentary contractility as well, in the hearts of patients suffering from left bundle-branch block or other intraventricular conduction disorders.
