患者男性,45岁。临床诊断:冠心病。图1A、B选自同一次动态心电图。图1A窦性心律与室性早搏交替出现成二联律。心房率59/min,P-R间期0.14s。图1B记录于图1A之后20min,窦性P频率71/min,下传的P-R间期分别为0.28s,0.32与0.38s此后脱落一个QRS波,又重复P-R递增现象。在QRS波脱落时,P-P显著延长,与中间有QRS波的P-P间期,相差>0.16s。心电图诊断:1.窦性心律不齐(室相性)2.室性早搏。3.2°I型房室阻滞。
Male patient, 45 years old. Clinical diagnosis: coronary heart disease. Figure 1A, B from the same dynamic electrocardiogram. Figure 1A sinus rhythm and premature ventricular contractions appear alternately as a dual law. Atrial rate 59 / min, P-R interval 0.14s. Figure 1B is recorded after 20 min of Figure 1A, sinus P frequency 71 / min, down P-R interval were 0.28s, 0.32 and 0.38s thereafter shed a QRS wave, and repeat the P-R increase phenomenon. In QRS wave shedding, P-P was significantly prolonged, with the QRS wave in the middle of the P-P interval, a difference of> 0.16s. ECG diagnosis: 1. Sinus arrhythmia (ventricular phase) 2. Premature ventricular contractions. 3.2 ° I-type atrioventricular block.
