近年来,随着心脏电生理研究的进展和射频消融术(RF-CA)在心律失常中的广泛应用,学者们对以前提出的Mahai m纤维的电生理表现及在心律失常中的作用有了更为深入的了解,提出了新的观点。目前认为在Mahai m纤维参与的心动过速中,以房束纤维引起者最为常见,递减传导的房室纤维相对 In recent years, with the progress of electrophysiological studies and the widespread use of radiofrequency ablation (RF-CA) in cardiac arrhythmias, scholars have suggested the electrophysiological findings and the role of arrhythmia in Mahai m fibers More in-depth understanding, put forward a new point of view. Currently considered Mahai m fiber involved in tachycardia, the fiber bundle fibers caused by the most common, decreased conduction relative to atrioventricular fibers
