本文报道两例室性早搏和一例Ⅲ°房室传导阻滞引起的室相性窦性心律不齐。其特点是紧跟有QRS波的P波与后面的P波之间的距离意外延长,与一般室相性窦性心律不齐的规律相反,故命名为室相性窦性心律不齐的变异型。
This article reports two cases of ventricular premature beats and a case of Ⅲ ° atrioventricular block caused by sinus rhythm. It is characterized by the QRS wave followed by the P wave and the back of the P wave of the unexpected increase in the distance between the general room phase sinus arrhythmia contrary to the law, so named room phase sinus arrhythmia variant.
