Right Atrial Pacing Impairs Cardiac Function During Resynchronization Therapy
OBJECTIVES We aimed to compare the hemodynamic effects of right-atrial-paced (DDD) and right-atrialsensed (VDD) biventricular paced rhythm on cardiac resynchronization therapy (CRT). BACKGROUND Cardiac resynchronization therapy improves hemodynamics in patients with severe heart failure and left ventricular (LV) dyssynchrony. However, the impact of active right atrial pacing on resynchronizatio...

متن کاملAcute haemodynamic benefits of biatrial atrioventricular sequential pacing: comparison with single atrial atrioventricular sequential pacing.
OBJECTIVE To evaluate the acute effects on haemodynamic variables of biatrial pacing in comparison with high right atrial (HRA) pacing and left lateral atrial pacing. PATIENTS AND DESIGN 23 patients were paced from the HRA site, the lateral site of the coronary sinus (CS), and both sites on two fixed atrioventricular delays (100 and 150 ms) during atrioventricular sequential pacing at 80 and ...
متن کاملCardiac Resynchronization Therapy; Biventricular Pacing
Although the estimates from limited studies vary on the proportion of patients with heart failure who also have ventricular dyssynchrony as reflected by a prolonged QRS complex, often in the form of left bundle branch block, the number of such patients is large (27% to 53%) and it is certainly in excess of the rate for the general population. Among these patients, 10% to 15% are candidates for ...
متن کاملpercutaneous repositioning of dislodged atrial pacing lead
the overall rate of atrial pacing lead dislodgement is estimated to be about 3%. these leads are generally repositioned via a second operation through opening the pacemaker pocket. some operators have introduced percutaneous techniques using snare system or deflectable catheters for this purpose. in this article we present our experience with five cases of percutaneous lead repositioning. three...
