Objective To study the relation between P wave dispersion, P wave width and paroxysmal atrial fibrillation.

目的研究心电图P波离散度、P波宽度与阵发性心房纤颤的关系。

The amplitude of wave before repeat wave and dicrotic wave obviously increased compared with vire pulse(P<0.01), but its width of main wave didn't increase greatly(P<0.01).

与弦脉比较，紧脉重搏前波波幅及降中波波幅增高明显（P＜0.01）；而主波宽度不如弦脉增加明显（P＜0.01）。
