关于心室预激的预激综合征(WPW 综合征)的既往研究表明,当 QRS 间期>140msec,心室预激程度可能最大,delta 波图形有助于旁道的定位.本文作者近期研究证实,窦性心律时即使心室预激未达最大程度,心电图对旁道定位诊断仍有重要价值。76例 WPW 综合征病人,均无多旁道和器质性心脏病,未服任何抗心律失常药物。全部病人作过电生理导管心内膜标测,其中45例手术治疗中进行计算机心外膜标测。将上述标测定位诊断结果与心电图对照,45例手术病人的心内膜与心外膜标测结果一致,仅30%病人的心电图 QRS 间期>140msec。 Previous studies on pre-excitation of WPW syndrome (WPW syndrome) showed that when QRS interval> 140msec, the amplitude of ventricular pre-excitation is probably the largest and delta wave pattern contributes to the positioning of the bypass.As the author of this paper has recently confirmed, Even if the sinus ventricular arrhythmia did not reach the maximum extent, ECG positioning on the diagnosis of the next pass is still of great value. 76 cases of WPW syndrome patients, no multiple bypass and organic heart disease, did not take any anti-arrhythmic drugs. All patients were performed electrophysiological endocardial mapping, of which 45 cases of surgical treatment of computer epicardium mapping. According to the electrocardiogram and electrocardiogram, the results of endocardium and epicardium in 45 surgical patients were consistent. Only 30% of the patients had QRS> 140msec.
