[Safety and effectiveness of single-lead VDD pacing].
INTRODUCTION AND OBJECTIVES Single-lead VDD pacing provides the physiological benefits of atrioventricular synchrony with the convenience of a single-lead system. However, concern remains about the method's safety and effectiveness. METHOD In total, 700 patients with single-lead VDD pacemakers were evaluated retrospectively. The following parameters were recorded: age, sex, etiology, the symp...
متن کاملRight atrial pacing impairs cardiac function during resynchronization therapy: acute effects of DDD pacing compared to VDD pacing.
OBJECTIVES We aimed to compare the hemodynamic effects of right-atrial-paced (DDD) and right-atrial-sensed (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 resynchroniza...
متن کاملLong-term follow-up of single-lead VDD pacing.
Long-term outcomes of single-lead VDD pacing were studied retrospectively and partly prospectively. Records were analysed of 81 patients out of 133 in whom a single-lead VDD pacemaker was implanted between January 1993 and December 1997 and who attended a follow-up clinic more than two years after the implant. Forty-eight of them attended a prospective follow-up 54 +/- 15 months after the impla...
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...
متن کاملSingle-Lead DDD Pacing: Is There a Difference Between a Right and Left Subclavian Approach?
reduced lead-related complication rate due to the use of one instead of two leads [8]. Despite a significant reduction in the atrial pacing threshold achieved by integrating the OLBI principle into single-lead DDD systems, several studies reported on a still relatively high incidence of atrial capture failure using the free floating atrial electrodes [9-14]. Since the ability to pace the atrium...
