摘要
目的 观察阵发性心房颤动的昼夜分布节律。方法 对阵发房颤的患者进行２４ 小时动态心电图及持续心电图监测观察其起始、持续和终止的节律变化。结果 阵发房颤的起始高峰时间发生在午夜至清晨３ 时。持续时间为凌晨４ 时至上午１１ 时，终止时间为中午及下午。结论 阵发性心房颤动起始、持续及终止有一定的昼夜分布节律，与自主神经及内源性生物活性物质的节律变化有关。
Objective To observe the circadian rhythm of paroxysmal atrial fibrillation. Methods Twenty-four-hour ambulatory electrocadiograms were recorded in 46 patients with paroxysmal atrial fibrillation in a drug-free state. To determine whether the onset,maintenance, and termination of paroxysmal atrial fibrillation were random events or have circadian rhythm. Results The onset of the arrhythmia was from midnight to 3 AM. Maintenance was from 4 AM to 11 AM. Termination showed a peak at noon and afternoon. Conclusion Paroxysmal atrial fibrillation shows a circadian rhythm that relates to circadian rhythm of autonomic nervous system and endogenous bioactivity agents.
