上两条为常规9个导联心电图,可见的异常表现为P-R段缩短,P-R间期约0.12s,胸导联均呈向上的单向波形,V_3较高大,V_3和V_5似见QRS波起始部粗钝,QRS波稍宽,约0.11s。下一条为食道心房调搏电生理检查的V_1导联记录,连续4次频率为120次/min的S_1剌激后,发放一次S_2刺激,S_1-S_2间距为0.44s,S_1和S_2以0.10s的S-R间期迅速下传心室,QRS波仍呈R型,但振幅显著
The above two conventional electrocardiogram for 9 leads, the abnormal performance of the PR segment shortening, PR interval of about 0.12s, chest leads showed upward unidirectional waveform, V_3 higher, V_3 and V_5 similar to see the QRS wave Begin blunt, QRS wave slightly wider, about 0.11s. The next one was recorded in the V_1 lead of esophageal atrial pacing electrophysiological examination. After S 4 stimulation at a frequency of 120 beats / min for 4 consecutive times, a S 2 stimulation was given, with S 1-S 2 spacing of 0.44 s, S 1 and S 2 at 0.10 s Of the SR interval quickly down the heart, QRS wave is still R-type, but significant amplitude
