心房扑动(房扑,AFL)是心电图问世以来人们认识最早的心律失常,但传统药物治疗不能很好地预防房扑的再发。近10年来,由于这种心律失常机制的进一步明确以及射频消融术(RF)的显著效果使房扑的治疗取得了新的进展。1历史回顾房扑首次报道于1886年。过去学者们认为房扑发生机制是由 Atrial flutter (atrial flutter, AFL) is the earliest known arrhythmia since the advent of electrocardiogram, but traditional drug therapy can not prevent the recurrence of atrial flutter. Nearly 10 years, due to the further clarification of this arrhythmia mechanism and the significant effect of radio frequency ablation (RF) made a new progress in the treatment of atrial flutter. A historical review of atrial flutter was first reported in 1886. In the past, scholars believe that the mechanism of atrial flutter is
