平板运动试验诱发冠心病患者心律失常分析

目的：分析平板运动试验诱发冠心病和非冠心病患者心律失常的情况。方法选取234例经冠状动脉造影的患者行平板运动试验，根据冠脉造影结果将其分为冠心病组（141例）和非冠心病组（93例），比较两组平板运动试验诱发心律失常的类型及特点。结果冠心病组心律失常发生率为42．55％（60／141），明显高于非冠心病组的15．05％（14／93），差异有统计学意义（P ＜0．05）。冠心病组心律失常构成类型：室性早搏26．95％、房性早搏5．67％、阵发性室速2．13％、阵发性房颤1．42％、右束支阻滞2．84％和短阵室速3．55％。结论平板运动试验既可诱发冠心病组发生心律失常，又可诱发非冠心病组发生心律失常，可用于冠心病的辅助诊断。

Analysis of arrhythmia induced by treadmill exercise test among patients with coronary heart disease

Objective To contrast the situation of arrhythmia induced by treadmill exercise test (TET)between patients with coronary heart disease(CHD)and non-CHD ones.Methods A total of 234 patients underwent TET,and were divided into CHD group(1 41 cases)and non-CHD group (93 cases)according to angiographic findings.The types and characteristics of TET-induced ar-rhythmia were compared between the two groups.Results The incidence of arrhythmia in CHD group was significantly higher than that in non-CHD group [42.55%(60 /1 41 )vs.1 5.05%(1 4 /93),P <0.05 ]. In CHD group, arrhythmias included premature ventricular contraction (26.95%),atrial premature beats(5.67%),paroxysmal aventricular tachycardia(2.1 3%),par-oxysmal atrial fibrillation(1 .42%),right bundle branch block(2.84%)and nonsustained ventricu-lar tachycardia(3.55%).Conclusion TET can not only induce arrhythmia in CHD group but also in non-CHD group.It is helpful in the auxiliary diagnosis of CHD.
