心房颤动(Af)是临床上常见的心律失常,可发生于各种心脏病、非心脏病及健康人,发生机制十分复杂,是目前心律失常和电生理研究领域中的热点和难点,自主神经系统的失衡、局灶性房性期前收缩的触发作用、局灶驱动源驱动心房的活动等都在不同程度上影响着Af的发生和维持[1]。心率变异性分析是目前常用无创性预测心脏自主神经功能变化的指标,本文通过对42例持续性Af合并糖尿病患者、例持续性无糖尿病患者心率变异性进行分
Atrial fibrillation (AF) is a clinically common arrhythmia, can occur in a variety of heart disease, non-heart disease and healthy people, the mechanism is very complex, is the current arrhythmia and electrophysiological research areas of hot and difficult, autonomic nerve The imbalance of the system, the triggering effect of focal atrial contractions and the action of focal drive source to drive the atria all affect the occurrence and maintenance of Af to varying degrees [1]. Analysis of heart rate variability is a commonly used noninvasive prediction of cardiac autonomic nerve function changes in this article through the 42 cases of persistent Af with diabetes, patients with persistent non-diabetic heart rate variability points
