摘要:
目的 探讨阵发性房室折返性心动过速(AVRT) 对人心房有效不应期(ERP) 的影响。方法 对55 例阵发性AVRT 患者, 采用S12S2 程控刺激法, 在AVRT 发生前及发生后, 分别测量其心房ERP。结果 AVRT 后即刻的ERP 较发生前缩短, 该缩短可在5 min 内恢复。AVRT 后5 和10min 的ERP 与AVRT 前比较无明显改变。结论 阵发性AVRT 能导致人心房ERP 缩短, 该缩短可在5 min 内恢复。
Abstract:
AIM To investigate the effects of paroxysmal atrio-ventricular reentrant tachycardia(AVRT) on human atrial effective refractory period (ERP). METHODS Fifty-five patients with paroxysmal AVRT were enrolled in this study. By means of S12S2 programmed stimulus, atrial ERP was measured before and after the occurrence of AVRT , respectively. RESULTS The ERP immediately after AVRT was markedly shortened in contrast with the one before AVRT , and restored to the basal level with in 5 min. However, there were no significant changes in the ERPs 5 and 10 min after AVRT. CONCLUSION Paroxysmal AVRT can shorten human atrial ERP,and this effects continues for 5 min.
