心脏的任何一个部分,不论是心房、房室结区(房室连接区)或心室的异位节律点,发出一次激动之后,再经过房室结区的另一个传导通路返回原处,再引起一次该处的除极,这样形成的搏动叫做反复性搏动,若连续发生3次以上叫做反复性心律(Reciprocal Rhytum),连续快速型反复性搏动叫做反复性心动过速 Any part of the heart, whether it is the atrium, atrioventricular node (atrioventricular junction) or ventricular ectopic rhythm point, after an excitement, and then through the atrioventricular node of another conduction path to return to the original place, and then cause Once the depolarization here, so the formation of the pulse is called repeated beats, if the continuous occurrence of more than 3 times called recurrent rhythm (Reciprocal Rhytum), continuous fast repetitive beats called recurrent tachycardia
