摘要:
目的:探讨风湿性心脏病(风心病)慢性心房颤动(AF)患者窦房结及房室结的功能。方法:3例风心病慢性AF患者在瓣膜手术时进行心外膜标测,电复律后测量窦房结和房室结功能。结果:28例电转复为窦性心律,成功率94%,28例中无1例有窦房结功能低下表现,窦房结恢复时间(SNRT)为(840.7±199.1) ms,矫正的窦房结恢复时间(SNRTc) 为(231.8±103.1) ms,房室结文氏点均在130 min-1以上,平均为(327.1±37.1) ms,房室结2∶1阻滞点均>150 min-1。结论:风心病慢性AF患者电复律后窦房结、房室结功能仍在正常范围,对于二尖瓣疾患合并慢性AF的患者应积极争取复律治疗。

Abstract:
investigate the sinus and atrioventricular node functions in patients with rheumatic heart disease combined with chronic atrial fibrillation (AF).Methods:Thirty rheumatic heart disease patients with chronic AF underwent epicardial mapping during valvular operation.The sinus and atrioventricular node functions were assessed after cardioversion.Results:Twenty-eight patients had their sinus rhythm restored after undergoing electrical cardioversion.The success rate was 94%.None of the 28 patients showed sinus and atrioventricular node hypofunction.The mean SNRT was (840.7±199.1) ms;mean SNRTc was (231.8±103.1) ms,all the atrioventricular Wenckebach points were over 130 min-1 with a mean value of (327.1±37.1) ms,all the atrioventricular conduction 2∶1 block were over 150 min-1.Conclusion:After the electrical cardioversion,the sinus and atrioventricular node functions of most rheumatic heart disease patients with chronic AF stay within the normal range.The results suggested that these patients should be given the opportunity to undergo cardioversion promptly.
