目的:探讨充血性心力衰竭(CHF)与心律失常的关系。方法:选择病因明确的CHF患者181例,记录分析每例患者常规和24h动态心电图,并于同日判定CHF类型和程度,测定血电解质浓度。比较CHF的不同病因、类型、程度、年龄及低血钾、低血镁与心律失常的关系。结果:CHF时心律失常发生率为81.2%;冠心病、心肌病组心律失常发生率高于其他病因组;左心衰和全心衰组心律失常发生率高于右心衰组;度心衰组心律失常发生率明显高于度心衰组;年龄≥60岁组心律失常发生率明显高于年龄≤39岁组;低血钾及低血镁组心律失常发生率高于正常血钾血镁(P均<0.05)。结论:CHF并发心律失常是多种因素共同作用的结果,应进行综合防治。
Objective: To investigate the relationship between congestive heart failure (CHF) and arrhythmia. Methods: A total of 181 CHF patients with definite etiology were selected. The routine and 24-hour ambulatory electrocardiogram (ECG) of each patient were recorded and analyzed. The type and degree of CHF were determined on the same day. The blood electrolyte concentration was measured. Compare the different etiology, type, degree, age of CHF and the relationship between hypokalemia, hypomagnesemia and arrhythmia. Results: The incidence of arrhythmia in CHF was 81.2%. The incidence of arrhythmia in CHD and cardiomyopathy group was higher than that in other etiologies. The incidence of arrhythmia in left heart failure and heart failure group was higher than that in right heart failure group. Group arrhythmia incidence was significantly higher than the degree of heart failure group; age ≥ 60-year-old group arrhythmia incidence was significantly higher than the age ≤ 39-year-old group; hypokalemia and hypomagnesemia arrhythmia incidence was higher than normal serum potassium (P <0.05). Conclusions: CHF complicated with arrhythmia is the result of many factors and should be controlled comprehensively.
