Biventricular Pacing in Congestive Heart Failure
Congestive heart failure (CHF) is a common, debilitating and usually lethal condition responsible for enormous burden on health care. The recent trials have shown improvement in morbidity and mortality with ACE inhibitors and beta blockers1-3. However, despite this the overall prognosis remains dismal. The other alternative of cardiac transplantation has several limitations including the donor ...
متن کاملProgression of heart failure in right univentricular pacing compared to biventricular pacing.
BACKGROUND Cardiac resynchronization therapy (CRT) improves hemodynamics and symptoms of heart failure by reducing ventricular dyssynchronity. Conversely, recent studies have demonstrated that right univentricular pacing in patients with an ejection fraction below 40% aggravates heart failure. In this retrospective study, we compared progression of disease in patients with mild to moderate hear...

متن کاملEffect of right ventricular versus biventricular pacing on electrical remodeling in the normal heart.
BACKGROUND Biventricular (BIV) pacing can improve cardiac function in heart failure by altering the mechanical and electric substrates. We investigated the effect of BIV versus right ventricular (RV) pacing on the normal heart. METHODS AND RESULTS Male New Zealand White rabbits (n=33) were divided into 3 groups: sham-operated (control), RV pacing, and BIV pacing groups. Four weeks after surge...
