受检者男性,74岁,心电图号2672。有30年心律不整史。心电图检查:图1上行为avR导联,下行为V_1导联。基本心律窦性,规整。本文只分析其心律失常的特征。下行第8个搏动为室性早搏。上行第3、7个,下行第2、5个搏动为房性早搏。这4个房性早搏的P′波与其前一个QRS波的距离(R-P′)以10毫秒为单位标示在图上,括号内的数字是房性早搏
Subject male, 74 years old, ECG number 2672. 30 years of irregular heart history. ECG examination: Figure 1 acts on the avR lead, the next act V_1 lead. Basic arrhythmia sinus, regular. This article only analyzes the characteristics of arrhythmia. Down the first eight beats premature ventricular contractions. The first 3,7 uplink, the second downlink 2,5 pulsatile atrial premature beats. The distance between the P ’wave of the four atrial premature beats and its previous QRS wave (R-P’) is shown on the graph in units of 10 milliseconds, with the numbers in parentheses indicating atrial premature beats
