患者男性,53岁,临床诊断:风湿性心脏病,主动脉瓣狭窄伴关闭不全,心功能Ⅲ级。心电图I 导联连续记录(附图)示窦P 规律出现,频率83次/min,并可见2种异位形态的室性搏动,均具有并行心律的特性,各有自己的频率,互不影响。一种QRS 波形较宽大,固有周期为1.60—1.72s,大多为1.64s。I a R_(10)形态介于窦性与室性之间,其前有窦P,P-R 间期为0.08s,比窦性激动P-R 间期缩短0.05s,为室性融合波。另一种QRS 波群振幅较低,固有周期为1.
Male patient, 53 years old, clinical diagnosis: rheumatic heart disease, aortic stenosis with insufficiency, cardiac function grade III. Continued recording of lead ECG (with photos) shows sinus P regularity, the frequency of 83 beats / min, and can be seen two kinds of ectopic ventricular beat, with the characteristics of parallel heart rate, each with its own frequency, without affecting each other . A larger QRS waveform, the natural period of 1.60-1.72s, mostly 1.64s. The morphology of I a R_ (10) was between sinus and ventricular. The anterior sinus P and P-R interval was 0.08s, which was shorter than that of sinus rhythm P-R interval by 0.05s. The other QRS complex has a lower amplitude and an eigenvalue of one.
