100例风湿性二尖瓣合并主动脉瓣病变患者的临床ECG分析表明,心房纤颤为最多见的心律失常(58.4％),其次有房室传导阻滞(18.3％),室性早博(13.0％),交界性早搏(3.9％)等。双瓣膜病变心房纤颤的发生率与性别、左室肥大无关(P>0.05)。房颤发生率增高且较对照组在统计学上有显著差异的因素是:年龄较大(≥45岁,69.7％,P<0.01),病程较长(≥10年,73.5％,P<0.01),有风湿活动(58.3％,P<0.01),心功能不全(>Ⅱ级,54.7％,P<0.01),无感染性心内膜炎(51.31％,P<0.05),左房增大(63.8％,P<0.05)。 Clinical ECG analysis of 100 patients with rheumatic mitral valve disease and aortic valve disease showed that atrial fibrillation was the most common arrhythmia (58.4%), followed by atrioventricular block (18.3%), ventricular premature beats 13.0%), borderline premature beats (3.9%) and so on. The incidence of bilateral valvular atrial fibrillation and gender, left ventricular hypertrophy (P> 0.05). The factors that increased the incidence of atrial fibrillation and were significantly different from the control group were: older age (≥45 years, 69.7%, P <0.01), longer duration (≥10 years, 73.5%, P <0.01 ) Had rheumatic activity (58.3%, P <0.01), heart failure (> Ⅱ grade, 54.7%, P <0.01), no infectious endocarditis (51.31%, P < (63.8%, P <0.05).
