左右心室各有一个异位节奏点并行竞争心室,产生正常波形的室性融合波,实属少见。现将我们遇到的一例报告如下。患者男性,56岁,冠心病,有晕厥史.心电图(附图)为V_1导联连续记录:P波与QRS无关,P-P基本规则,频率为56次/分,QRS形态变化较大,有数种形态,其中两种较为同定,一种呈左束支阻滞(LBBB)型,一种呈右束支阻滞(RBBB)型,此两种QRS宽0.12秒,频率非常接近,分别为29-30次/分和29-31次/分.其余QRS形态除个别表现
Left and right ventricles each have a rhythm of ectopic competition in parallel ventricular, resulting in normal waveform of ventricular fusion waves, it is rare. Now we have a case report is as follows. Patients with male, 56 years old, coronary heart disease, a history of syncope. ECG (with photos) continuous recording for the V_1 lead: P wave and QRS has nothing to do, PP basic rules, frequency of 56 beats / min, QRS morphology changes, (LBBB) and a type of RBBB (Right Bundle Branch Block). The two QRSs are 0.12 seconds wide and have very similar frequencies of 29- 30 beats / min and 29-31 beats / min The rest of the QRS modalities, except for individual performance
