在 W·PW 综合征鉴别诊断中两个较难解决的问题,其一是预激波可能掩盖或误诊为心肌梗塞、室内传导阻滞、心室肥大等较严重的心电图改变;其二是在伴发室上速、房扑、房颤中当旁路呈前向传导时,QRS 明显宽大畸形极易误诊为室速。虽然临床资料和心电图的致细分析对鉴别诊断有一定帮助,但最可靠的方法:对前者是设法消除预激波;而对后者是设法诱现完全性心室预激波形。文献中虽然提到用药物等方法消除或诱
One of the more difficult problems in the differential diagnosis of W · PW syndrome is that the pre-shock may mask or misdiagnose more serious ECG changes such as myocardial infarction, ventricular block, and ventricular hypertrophy. Fat room on the speed, atrial flutter, atrial fibrillation in the bypass was anterior conduction, QRS obvious large deformity easily misdiagnosed as VT. Although careful analysis of clinical data and electrocardiogram may be helpful in differential diagnosis, the most reliable method is to try to eliminate the pre-shock in the former and try to induce the complete pre-excitation waveform in the latter. Although the literature mentions the use of drugs and other methods to eliminate or lure
