摘　　要：目的　报告一种新型的室上性心动过速 ;方法　总结该心动过速的电生理特点及射频消融治疗方法 ;结果　该型室上速的发生机制是窦性激动连续经房室结 1:2下传激动心室 ,导致心室率经常是心房率的两倍 ,心动过速呈无休止性发作 ,并引起心动过速性心肌病。Objective To report a new type of superventricular tachycardia; Methods Analysed electrophysiology characteristic of the tachycardia induced by dual atrioventricular nodal pathways;Results The mechanism of the tachycardia is 1:2 AV conduction by dual atrioventricular nodal pathways, the ventricular rate is often two times of the atrial rate, and the tachycardia is incessant, and the patient suffered from the tachycardia cardiomyopathy;Conclusion The tachycardia can be diagnosed by electrophysiology studying and cured by radiofrequency ablation.
