Clinical significance of change on ventricular rate in patients with persistent atrial fibrillation patients / 中国基层医药

ABSTRACT

Objective To discuss the significance of ventricular rate for patients with persistent a trial fibrillatio. Methods Patients with persistent atrial fibrillation more than 1 year were divided into cerebral embolism group (34 patients)and non- cerebral embolism group(32 patients). The data of patients in two groups were collected and compared ,including general clinical characteristics ,the highest ,lowest and average ventricular rate detected by Holter monitor system,left atria diameter and left ventricular ejecting fraction measured by echocardiography. Results There was no significant difference between two groups about general clinical characteristics, left atria diameter(P ＞ 0. 05).The highest, lowest and average ventricular rate were higher in cerebral embolism group than those in non-cerebral embolism group(P ＜ 0. 05). However, left ventricular ejecting fraction was much lower in cerebral embolism group( P ＜0. 05 ). Conclusion It is critical to control heart rate for patients with persistent atrial fibrillation to prevent cerebral embolism and left ventricular function.
