临床资料患者女性,41岁,临床诊断:心肌炎。心电图(附图)为Ⅱ导联连续描记,各导联仅有少数直立之窦性P波,有时单个发生,有时连续发生,其间有或长或短的窦性停搏(其长P-P间期不是短P-P间期的整数倍),停搏时发生交界性逸搏或交界性逸搏心律(Ⅱc～Ⅱd段)。罕见的是交界性逸搏心律频率逐渐加快的同时尚可见R-P′间期(为测量准确,本例以QRS起始部至逆P最低点为测量标准)由0.16s逐渐缩短至0s(二者重叠)。另外有部分交界性逸搏后出现一提前发生的窦性激动,但其P波有时低平或倒置,致使P-R间期不易测准,但其QRS波形态与窦性者相同,而与交界性逸搏之QRS波有微小差异,根据Ⅱa末尾2个P′-P关系,推测可能系
Clinical data Patients Female, 41 years old, clinical diagnosis: myocarditis. Electrocardiogram (with photos) for the Ⅱ lead continuous tracing, each lead has only a small number of echogenic sinus P wave, and sometimes a single occurrence, sometimes continuous, during which there is a long or short sinus arrest (its long PP interval Not an integer multiple of the short PP interval), arrhythmia of borderline escaping or borderline escaping at arrest (IIc-IId). Rare is the junctional esophageal escape rhythm frequency is gradually accelerating at the same time can be seen RP ’interval (for the measurement accuracy, in this case starting QRS start point to the inverse P minimum as the measurement standard) gradually reduced from 0.16s to 0s (both overlapping). Another part of the junctional esophageal sinus occurred after a premature sinusitis, but the P wave sometimes flat or inverted, resulting in PR interval is not easy to measure, but the QRS wave morphology and sinus are the same, and with the borderline Yat stroke QRS wave with small differences, according to Ⅱ a at the end of two P’-P relationship, suggesting that the possible line
