Abstract：Objective To investigate the effect of rate adaptive dual-chamber pacemaker on exercise capacity and quality of sexual activity in male patients with third-degree atrioventricular block.Methods We randomly assigned 170 male patients with third-degree atrioventricular block to DDDR group (n =106) and control group (n =64).At the baseline and post treatment,we assessed the international index of erectile function (IIEF-5) and frequency of sexual activity.At the same time,6 min walking test (6MWT) was recorded.The distance and heart rate of 6MWT were measured; left ventricular ejection fraction (LVEF) and cardiac output were also calculated.Results Compared with the control group,The IIEF-5 score,sexual satisfaction and frequency of sexual activity [(20 ± 6) scores vs (16 ± 5) scores,(4.6 ± 1.3) scores vs (2.6 ± 1.6) scores,(6.1 ± 2.9) times/month vs (3.4 ± 1.7) times/month] had a significant increase in DDDR group after treatment (P ＜ 0.05).Compared with the control group,the distance and heart rate of 6MWT and cardiac output in DDDR group significant increased [(528±106)m vs (379 ±75)m,(127 ± 9) times/min vs (51 ± 8)times/min,(4.8 ±0.7)times/min vs (3.9 ±0.5)times/min] ; there was a significant difference between the DDDR group and control group (P ＜ 0.05).Conclusions Among male patients with third-degree atrioventricular block,those treated with DDDR have improvements in exercise capacity and quality of sexual activity than control group.These improvements are positively associated with increases in exercise capacity during sexual intercourse.
