脑出血患者植物神经功能昼夜变化规律分析

Analysis Circadian Rhythm of Autonomic Nerve Activity of Patients with Cerebral Hemonhage

采用２４ 小时动态心电图记录３８ 例脑出血急性期患者（脑出血组）及３０ 例正常人（对照组）的心率变异性（ＨＲＶ）指标及心律失常昼夜变化。结果：脑出血组ＨＲＶ失去昼夜节律变化，昼夜总心率变异性降低，室性早搏、室上性早搏明显增多；白天以交感神经受损明显，交感、迷走神经失去平衡；夜间交感、迷走神经均明显受损，但二者保持平衡；２２时至次日６ 时迷走神经张力最高，但亦低于正常人。

The heart rate variability(HRV)and arrhythmia of 38 acute cerebral hemorrhage(cerebral hemorrhage group)and 30 healthy people(control group)were recorded using 24 hours ambulatory electrocardiogram The results showed that the circadian oscillation of HRV in the acute phase of cerebral hemorrhage cases was lost,the sympathetic activity was significantly reduced during day and both the sympathetic and parasympathetic activities were markedly reduced at night Both at night and during day,the ventricular premature contruction and supraventricular premature Contrution were more than that of the controls
