所谓假性心室性心动过速原指心房颤动或心房扑动而伴有预激症候群。当传导通过房室结的异常通路合併室阻滞时可以出现相似的图形,这个术语包括各型房室传导阻滞伴房室结异常通路。阵发性假性心室性心动过速根据QRS综合波的形态、规则性,而有不同的临床意义,如QRS综合波既宽大又不呈现预激波形,往往表示病变在希氏束远端以下,病情重。关于阵发性假性心室性心动过速的心电图诊断范围,由阵发性房性心动过速,心房扑动或颤动伴异常通路而出现高度快速性心室率,心率每分钟在200～240次或以上,
The so-called pseudo-ventricular tachycardia originally refers to atrial fibrillation or atrial flutter associated with pre-shock syndrome. A similar pattern can occur when anomalous passages that pass through atrioventricular node block the block, and the term includes various types of atrioventricular block with abnormal atrioventricular node pathways. Paroxysmal pseudo-ventricular tachycardia QRS complex according to the shape of the waveform, regularity, and have different clinical significance, such as QRS complex wave is neither large nor pre-excitation waveforms, often said lesion below the His bundle far , The condition is heavy. About paroxysmal pseudo-ventricular tachycardia ECG diagnostic range, paroxysmal atrial tachycardia, atrial flutter or fibrillation with abnormal pathways and the emergence of a rapid ventricular rate of heart rate at 200 to 240 beats per minute or above,
