ABSTRACT
Objective To investigate the impact of paced QRS duration (pQRSd) on heart function in patients with right ventricular apical pacing. Methods Seventy-six patients with Ⅲ° atrioventricular block received pacemaker treatment were enrolled and randomized into group A (pQRSd 0.05). At 24 months after implanting, LAD、LVEDD、LVESD of group B increased significantly compared with those of group A [LAD,( 44.5 ± 6.2) mm vs (41.6 ± 5.1) mm, LVEDD, (52.7 ± 9.3) mm vs (48.2 ± 7.5) mm, LVESD, (37.5 ± 5.6) mm vs (33.8 ± 4.9)mm, each P 0.05)between two groups during 24-month follow-up. Conclusion The prolonged paced QRS duration has a detrimental effect on long-term cardiac function during RVA pacing in patients with Ⅲ°atrioventricular block.
