当心电图上P_(ⅡⅢAVF)倒置P_(AVR)直立时一般称为逆行P(简称P′),如出现于正常QRS波之前P′R<0.12″时,见于房室交界处心律,如P′R>0.12″称房室交界处心律伴下行一度传导阻滞,有的认为是冠状窦性心律,多数具有病理意义,临床上常见于患心肌炎、冠心病、心肌梗塞、洋地黄中毒时。但此时必需与少见的左心房心律相区别。左心房心律可见于健康人,亦可见于器质性心脏病,但与任
When ECG P_ (Ⅱ Ⅲ AVF) inverted P_ (AVR) upright is generally called retrograde P (P ’for short), such as P’R <0.12 before the normal QRS wave seen in the atrioventricular junction rhythm, such as P’ R> 0.12 "at the junction of the atrioventricular junction with the conduction line once the block, and some believe that coronary sinus rhythm, the majority of pathological significance, clinically common in patients with myocarditis, coronary heart disease, myocardial infarction, digitalis poisoning. But this time must be different from the rare left atrial rhythm. Left atrial rhythm can be seen in healthy people, can also be found in organic heart disease, but with any
