Acute comparative effect of right and left ventricular pacing in patients with permanent atrial fibrillation.
We tested the hypothesis that left ventricular (LV) pacing is superior to right ventricular (RV) apical pacing in patients undergoing atrioventricular (AV) junction ablation and pacing for permanent atrial fibrillation. The potential benefit of LV over RV pacing needs to be evaluated without the confounding effect of other variables that can influence cardiac performance. An acute intrapatient ...
متن کاملShortening of paced QRS complex and clinical improvement following upgrading from apical right ventricular pacing to bifocal right ventricular or biventricular pacing in patients with permanent atrial fibrillation.
BACKGROUND Cardiac resynchronisation therapy (CRT) using biventricular pacing (BVP) has been shown to improve survival in patients with chronic heart failure (CHF). However, BVP cannot be achieved in all patients because of technical problems. In such patients, bifocal right ventricular pacing (BFP) may be an alternative. AIM To analyse the relationship between changes in paced QRS complex wi...
متن کاملBiventricular pacing decreases sympathetic activity compared with right ventricular pacing in patients with depressed ejection fraction.
BACKGROUND Although there have been few studies in which the hemodynamic effects of right ventricular (RV) and left ventricular (LV) pacing were compared with those of biventricular (BV) pacing, the autonomic changes during these different pacing modes remain unknown. We hypothesized that BV pacing results in improved hemodynamics and a decrease in sympathetic nerve activity (SNA) compared with...
متن کاملVentricular remodeling in right ventricular apical pacing.
OBJECTIVE To determine ventricular remodeling (VR) and the role of clinical and functional variables in patients with normal cardiac function who underwent right ventricular apical pacing (RVAP). METHODS Among the 268 consecutive patients with standard pacemaker due to complete atrioventricular block (CAVB), those with left ventricular ejection fraction (LVEF) < 55% and left ventricular end-d...
متن کاملSurvival analysis in patients with preserved left ventricular function and standard indications for permanent cardiac pacing randomized to right ventricular apical or septal outflow tract pacing.
BACKGROUND Optimal right ventricular (RV) pacing site in patients referred for permanent cardiac pacing remains controversial. A prospective randomized trial was done to compare long-term effect of permanent RV apex (RVA) vs RV outflow tract (RVOT) pacing on the all-cause and cardiovascular mortality. METHODS AND RESULTS A total of 122 consecutive patients (70 men, 69 +/-11 years), with stand...
