对１１例ＳＳＳ患者安置了生理性起搏器，其中７例应用彩色三维超声心动图比较了心房按需型起搏（ＡＡＩ）、房室顺序起搏（ＤＶＩ）与单心室按需起搏（ＶＶＩ）三种不同起搏方式的血液动力学改变。结果显示ＡＡＩ、ＤＶＩ起搏较ＶＶＩ起搏每搏量明显增加分别达３７％、２０％（Ｐ＜０．０１）。通过程控调测、胸壁抑制试验、ＤＣＧ等定期随访患者心律失常及房室传导阻滞变化情况，在平均２０多个月的随访中尚未发现新的快速房性心律失常和传导阻滞，原有的房性心律失常也得到较好控制。认为ＳＳＳ患者的生理性起搏与ＶｖＩ起搏比较可产生较好的血液动力学效果，新的快速性房性心律失常及房室传导阻滞的发生率较低，因此对有适应症的ＳＳＳ患者应尽量选用。
Physiological pacemakers were placed on 11 patients with SSS. Seven of them compared color Doppler echocardiography with AAI, DVI and single ventricular on-demand pacing VVI) hemodynamic changes in three different pacing modes. The results showed that the pacemaker volume of AAI and DVI was 37% and 20% higher than that of VVI pacing (P <0.01). Through routine testing, chest wall suppression test, DCG and other regular follow-up of patients with arrhythmia and atrioventricular block changes in the average of more than 20 months of follow-up has not found a new rapid atrial arrhythmia and conduction block, the original Atrial arrhythmias are also well controlled. Physiological pacing in patients with SSS and VvI pacing that can produce better hemodynamic effects, the new rate of atrial tachyarrhythmia and atrioventricular block incidence is low, so the indication of SSS Patients should try to use.
