不对称的传导、单向阻滞、与局部传导速度迟缓所形成的折返现象较自律性增强似乎是发生心律不齐的更重要原因,但是心律不齐的病理学是复杂的,所以引起心律紊乱的条件与使其持续改变的情况可以是完全不同的,中枢与自主神经系统对心律不齐的发生与持续是有明显影响的。研究旁路传导折返机理可了解交接区性与反复性心动过速,在非发作时的心电 Asymmetric conduction, unidirectional blockade, and increased autonomic reflexes as a result of slow local conduction velocity appear to be more important causes of arrhythmia, but the pathology of arrhythmia is complex and therefore causes arrhythmia Conditions and conditions to make it a continuous change can be completely different, central and autonomic nervous system arrhythmia occurrence and persistence have a significant impact. Study of bypass conduction reentry mechanism to understand the transfer of regional and recurrent tachycardia, non-attack of the ECG
