本文连续对9例无快速型心律失常的窦房结综合征(SSS)患者心室永久起搏治疗前后的窦房结功能进行系统观察和检查。1例起搏12个月后变为持续性房颤;另8例平均起搏23.0±15.1个月后在胸壁刺激(CWS)时重复食道调搏,其中1例虽已恢复正常窦性心律,但该例动态观察结果以及整个8例起搏治疗前后的窦性停搏时间,BSL、IHRo、SNRT、SNRT_c,SNRT_I及继发性停搏时间均无显著差别(P>0.05),提示心室永久起搏治疗难以使SSS患者的窦房结功能真正好转和恢复。
In this paper, we systematically observed and examined the function of sinoatrial node before and after ventricular perpetual pacing therapy in 9 patients with tachyarrhythmia of sinus node syndrome (SSS). 1 case of persistent atrial fibrillation after 12 months of pacing; the other 8 cases of average pacing 23.0 ± 15.1 months after chest wall stimulation (CWS) repeat esophageal pacing, of which 1 cases have returned to normal sinus rhythm, However, there was no significant difference between BSA, IHRo, SNRT, SNRT_c, SNRT_I and secondary arrest time in the dynamic observation and the sinus arrest time before and after pacing in 8 patients (P> 0.05) Pacing treatment is difficult to make SSS patients really improve the function of the sinus node and recovery.
