患者女,41岁,因心律失常原因待查住院。心电图见附图。诊断:窦性心律,多源性、频发性、房性早搏伴心室内差异性传导。图1 为 V_1导联。P′_3P′_4下传之 QRS 呈rsR′形,时间为0.12秒,呈完全性右束支阻滞图形。P′_2下传之 QRS 波与窦性下传者略有差异。图2 Ⅰ、Ⅱ、Ⅲ导联为同步记录,图中房早 Female patient, 41 years old, due to arrhythmia pending hospitalization. ECG see attached map. Diagnosis: sinus rhythm, multi-source, frequent, atrial premature beats with ventricular differential conduction. Figure 1 for the V_1 lead. The QRS of P’_3P’_4 was rsR ’shaped with a time of 0.12 seconds, showing a complete right bundle branch block pattern. There is a slight difference between the QRS wave transmitted on P’_2 and the sinus beacons. Figure 2 Ⅰ, Ⅱ, Ⅲ lead for the synchronization record, the picture in the room early
