Background—Previous studies of pacing therapy for dilated congestive heart failure (CHF)
have not established the relative importance of pacing site, AV delay, and patient …

Objectives : We sought to compare the short- and long-term clinical effects of atrial
synchronous pre-excitation of one (univentricular) or both ventricles (biventricular), that provide …

Background— Cardiac resynchronization therapy (CRT) improves systolic function in heart
failure patients with ventricular conduction delay by stimulating the left ventricle (LV) or both …

Objectives : We studied the acute effects of cardiac resynchronization therapy (CRT) on
functional mitral regurgitation in heart failure (HF) patients with left bundle branch block (LBBB). …

Objectives : We sought to investigate the impact of six months of cardiac resynchronization
therapy (CRT) on echocardiographic variables of left ventricular (LV) function. Background : …

Objectives : We assessed the clinical efficacy of single-site left ventricular (LV) pacing and
determined the impact of baseline conduction delay severity on the magnitude of benefit. …

In conjunction with pharmacologic therapy, pacing has been proposed as a potential treatment
to decrease symptoms in patients with moderate-to-severe congestive heart failure (CHF)…

Background—After cardioversion of atrial fibrillation (AF), the contractile function of the atria
is temporarily impaired. Although this has significant clinical implications, the underlying …

European Heart House, headquarters of the ESC. Any changes in conflict of interest that
arise during the writing period must be notified to the ESC. The Task Force report was entirely …

Objectives : We studied the effects of cardiac resynchronization therapy (CRT) on heart
failure (HF) patients with central sleep apnea (CSA). Background : Patients with advanced HF …
