The effects of right ventricular apical pacing on ventricular function and dyssynchrony implications for therapy.
Cardiac pacing is the only effective treatment for patients with sick sinus syndrome and atrioventricular conduction disorders. In cardiac pacing, the endocardial pacing lead is typically positioned at the right ventricular (RV) apex. At the same time, there is increasing indirect evidence, derived from large pacing mode selection trials and observational studies, that conventional RV apical pa...
متن کاملSimultaneous His Bundle and Left Ventricular Pacing for Optimal Cardiac Resynchronization Therapy Delivery
The beneficial effects of cardiac resynchronization therapy (CRT) have been evaluated in several trials, and different degrees of response to CRT have been reported; indeed, the optimization of pacing sites and stimulation timing seems to be a major determinant of the hemodynamic response. For standard CRT delivery, the atrioventricular pacing interval is shortened to ensure consistent left ven...
متن کاملBifocal pacing in the right ventricle: an alternative to resynchronization when left ventricular access is not possible in end-stage heart failure patients.
BACKGROUND It has been reported that bifocal pacing (BiF) in the right ventricle might be an alternative to unsuccessful left ventricular lead implantation. This case report presents an assessment of the clinical and hemodynamic parameters during a three month follow-up in patients implanted with right ventricular BiF. METHODS Eight patients who underwent unsuccessful left ventricular lead im...
متن کاملSimultaneous His Bundle and Left Ventricular Pacing for Optimal Cardiac Resynchronization Therapy Delivery: Acute Hemodynamic Assessment by Pressure-Volume Loops.
BACKGROUND Previous studies have investigated the role of intrinsic conduction in optimizing cardiac resynchronization therapy. We investigated the role of fusing pacing-induced activation and intrinsic conduction in cardiac resynchronization therapy by evaluating the acute hemodynamic effects of simultaneous His-bundle (HIS) and left ventricular (LV) pacing. METHODS AND RESULTS We studied 11...
متن کاملEarlier Right Ventricular Pacing in Cardiac Resynchronization Therapy for a Patient with Right Axis Deviation
We describe the case of a 37-year-old woman who presented with complete right bundle branch block and right axis deviation. She was admitted to our hospital due to severe heart failure and was dependent on inotropic agents. Cardiac resynchronization therapy was initiated but did not improve her condition. After the optimization of the pacing timing, we performed earlier right ventricular pacing...
