病态窦房结综合征患者房室传导功能分析

Analysis of atrioventricular conduction function in patients with sick sinus syndrome

为了解病态窦房结综合征患者的房室传导功能,用食管电生理检查观察窦房结功能正常者86例、窦房结功能低下者40例和病态窦房结综合征者109例的房室传导功能.结果显示:3组的文氏型阻滞点、2:1阻滞点差异无显著意义(P>0.05).将窦房结功能障碍者的窦房结恢复时间与文氏型阻滞点、2:1阻滞点作相关分析,结果均无相关性(P>0.05).认为病态窦房结综合征发生房室传导阻滞的概率较低,植入起搏器前应作食管心房调搏检查房室传导系统功能.

To investigate value of recognition of atrioventricular conduction function by noninvasive methods to clinical treatments of sick syndrome and correct selection of pacemaker types, atrioventricular conduction function in 235 patients were analyzed by transesophageal electrophysiological stusies(86 cases of normal sinus function, 40 cases of sinus dysfunction, 109 cases of sick sinus function) .Results showed that differences of Wenckebach block point and 2 : 1 block point were insignificant among normal group. Sinus dysfunction group and sick sinus syndrome (P > 0.05), sinus recovery time were not related to Wenckebach block point and 2 : 1 block piont in patients with sick sinus syndrome(P> 0.05) .This study suggests that prevalence atrioventricular conduction block is low in patients with sick sinus syndrom and that recognition of atrioventricular conduction functions by transesophageal atrial pacing before pacemaker implanting were rational.
