本文分析216例风心中窦性、房性、房室交界性、室性心律失常和冲动传导失常的发生率,其中,房性心律失常发生率最高(49.54％)。统计学处理显示,三种风心(二尖瓣病变、主动脉瓣病变、二尖瓣合并主动脉瓣病变)中发生房性、交界性、室性心律失常和传导失常的差异分别是P<0.01P>0.05、P<0.01和P>0.05。风心中房颤发生率最高(43.52％),房颤与左房大小密切相关。本文论述了风心发生心律失常的机理。 The incidence of sinus, atrial, atrioventricular junction, ventricular arrhythmia and impulse conduction disorders were analyzed in 216 patients. Among them, the incidence of atrial arrhythmia was the highest (49.54%). Statistical analysis showed that the three kinds of wind heart (mitral valve disease, aortic valve disease, mitral valve disease with aortic valve disease) occurred in atrial, borderline, ventricular arrhythmia and conduction disorders were P < 0.01 P> 0.05, P <0.01 and P> 0.05. The highest incidence of atrial fibrillation (43.52%), atrial fibrillation and left atrial size are closely related. This article discusses the mechanism of cardiac arrhythmia.
