预激综合征(简称预激征)可引起多种快速性心律失常,包括致死性的房颤和室颤;它的多变的图形又常可冒充或掩盖一些常见的心电图异常(包括束支阻滞、心室肥厚和心肌梗塞)造成诊断上的困难,故有“大伪装者”之称。近年来由于外科手术治疗预激征病人取得显著成功,对本病的诊断要求大大地提高。心内电生理检查在提高预激征诊断的准确性,副束的定位诊断、鉴定其伴发心律失常的性质及副束在这些心律失常发生机理中所起的作用、研究副束的电生理特性、评价各种治疗手段等方面都可以提供很有价值的资料,但由于它是一种创伤性检查,技术设备条件
Wolff-Parkinson’s syndrome (pre-excitation syndrome) can cause a variety of tachyarrhythmia, including lethal atrial fibrillation and ventricular fibrillation; its changing shape and often can mask or mask some common ECG abnormalities Hysteresis, ventricular hypertrophy and myocardial infarction) cause diagnostic difficulties, it is “big disguise” said. In recent years due to surgical treatment of pre-excitation patients achieved significant success, the diagnosis of the disease greatly increased. Intracardiac electrophysiological examination in improving the accuracy of the pre-excision diagnosis, the diagnosis of accessory fascia, identify the nature of its associated arrhythmias and the role of the accessory bundle in the mechanism of these arrhythmias, the study of the accessory-bundle electrophysiology Characteristics, evaluation of various treatment methods can provide valuable information, but because it is a traumatic inspection, technical equipment conditions
