阵发性心房颤动患者动态心电图的临床分析

目的：探讨阵发性心房颤动（paroxysmal atrial fibrillation，PAF）的发作持续时间有无昼夜分布节律及其与患者性别、年龄和左房内径的关系。方法选取在我院住院或门诊行24 h动态心电图检查的66例 PAF 患者（PAF 组），并随机选择60例住院患者（对照组），均经动态心电图检查排除心房颤动。分析 PAF 组患者的动态心电图数据，统计每个时间段房颤持续的时间，同时比较两组的性别、年龄和左房内径等。结果PAF 的发作与维持有昼夜分布节律，与患者的年龄、左房内径等关系密切。结论动态心电图检测 PAF 操作简便、安全可靠、可重复性好，值得临床推广与应用。

Clinical analysis on ambulatory electrocardiography of patients with paroxysmal atrial fibrilla-tion

Objective To explore whether there exists circadian rhythm in the duration of paroxys-mal atrial fibrillation(PAF)and the relationship between PAF and gender,age and left atrial diameter (LAD).Methods In our study,PAF group consisted of 66 PAF inpatients or outpatients who had undergone 24-hour ambulatory electrocardiography(AECG)examination in our hospital.Another 60 inpatients were randomly selected as control group with atrial fibrillation (AF)excluded by AECG ex-amination.Among 66 PAF cases,AECG data were analyzed and the duration of AF in each time peri-od was recorded.At the same time,we compared gender,age and LAD between the two groups.Re-sults The onset and duration of PAF followed circadian rhythm and were closely related to PAF patient's age,LAD and other factors.Conclusion AECG examination is worthy of being popularized in PAF patients for its simplicity to operate,safety,reliability and good reproducibility.
