患者女性,39岁,主诉头晕、眼黑,心悸一年余,体检发现心律不齐,诊断特定.Ⅰ导联连续记录(附图)可见窦性心律,P-P间距不规则,长P-P间距略小于短P-P间距的两倍,可能是Ⅱ°二型窦房阻滞.QRS波有三种形态.第一种左束支阻滞型(R型),由窦性与交界性逸搏下传;第二种右束支阻滞型(qRs型),联律间期不等,各右束支阻滞波形之间呈倍数关系,如
Female patient, 39 years old, complained of dizziness, dark eyes, palpitations more than a year, physical examination found arrhythmia, diagnosis specific. Ⅰ lead continuous recording (with photos) shows sinus rhythm, PP spacing irregularity, PP twice the space, may be Ⅱ ° two sinoatrial block.QRS wave has three forms.The first left bundle branch block type (R type), by the sinus and junction escapement; Second Right bundle branch block type (qRs type), associated with the law between the interval, the right bundle branch block waveforms between the multiple relationship, such as
