老年特发性阵发性心房颤动患者的动态心电图分析

目的 观察了解老年人特发性阵发性心房颤动与生理性退行性变的关系。方法采用动态心电图对36例无器质性病因的老年人阵发性心房颤动进行24h监测，并对阵发性心房颤动发作的时间、发生的频率、心率的变化、合并其他的心律失常进行统计。结果老年人阵发性心房颤动发作前后多并有心律失常，尤其是室上性心律失常占首位；大多数发作时心室率较慢；发作时间存在昼夜节律，有两个高峰和一个低谷。结论老年人特发性阵发性心房颤动与心房肌、房室交界区生理性退行性变有直接关系，也提示与迷走神经兴奋性的增高及隐匿性传导有关。

The dynamic electrocardiogram analyse in the elderly paroxysmal auricular fibrillation

Objective To explore the relations between physiological retrogressive auricular fibrillation and organical pathological auricular fibrillation in elderly patients. Methods 36 cases paroxysmal auricular fibrillation in elderly patients without organical pathogeny were monitored for 24 hours using dynamic electrocardiogram. The attack time and frequency of paroxysmal auricular fibrillation,the change of heart rate,and other type arrhythmia complexing were analyzed. Results Most cases of paroxysmal auricular fibrillation in elderly patients were companied with arrhythmia,supravenrricular arrhythmia occupy in the first place especially. The ventricle rate was slow in most cases. The attack had different rhythm in day and night, there were two flows and one edd in one day. Conclusion The elderly auricular fibrillation is associated with the physiological anaplasia of auricular muscle and artro-vcntricular junction area directly, it also relates to the heighten excitability of pneumogastric nerve and se.cretive conduction.
