     [摘要]目的：运用中医时间医学理论阐释病毒性心肌炎患者室性早搏24 h的分布规律，为确定合理的给药时间提供科学的依据。方法：240例病毒性心肌炎患者行24 h动态心电图监测，运用中医五脏主时节律等理论对患者室性早搏分布的节律性变化进行研究。结果：病毒性心肌炎患者室性早搏普遍高发于寅、卯、辰、巳四个时辰，尤以卯时为甚；酉、戌、亥三个时辰为室性早搏发生的低谷时段。随着年龄的增长，病毒性心肌炎患者室性早搏夜半时段的发生频度增加。不同证型的病毒性心肌炎患者其室性早搏发作的高峰时段不同。邪热犯心证患者，室性早搏多高发于日中时段；阴虚火旺证患者，室性早搏多高发于白天，日中时段加重；心气阳虚证患者，室性早搏多高发于平旦和夜半时段。结论：病毒性心肌炎患者室性早搏日分布具有明显的中医病理节律，不同证型的室性早搏，其日分布的节律亦不相同，可指导临床辨证施治。

    ABSTRACT Objective: To explore the circadian distribution of premature ventricular contractions (PVCs) in patients with viral myocarditis (VM) according to the theory of chronomedicine in traditional Chinese medicine (TCM) in order to find out the scientific evidence for a reasonable administration time. Methods: Two hundred and forty patients with VM were enrolled and electrocardiograms were examined for all by Holter monitor. The circadian distribution of PVCs was evaluated according to the theory of chronomedicine of TCM about time periods corresponding to five zang viscera. Results: PVCs mostly happened in periods of 3∶00–5∶00, 5∶00–7∶00, 7∶00–9∶00 and 9∶00–11∶00, in which 5∶00–7∶00 was the most serious time. Less PVCs happened in periods of 17∶00–19∶00, 19∶00–21∶00 and 21∶00–23∶00. The frequency of PVCs in midnight also increased with aging. The time periods of the frequency peak of PVCs in patients with different syndromes were also different. In patients with syndrome of pathogenic heat invading heart (PHIH), the PVCs mostly appeared in midday. In patients with syndrome of flaring of fire due to yindeficiency (FFYD), the PVCs were most serious in daytime and aggravated at noon. And in patients with syndrome of insufficiency of heartqi and yang (IHQY), the PVCs mostly happened in early morning or midnight. Conclusion: There was a manifest regulation of the pathological circadian rhythm of PVCs in patients with VM. The circadian distributions of PVCs were variable in patients with different syndromes. Therefore the theory of chronomedicine of TCM may be used to guide the treatment based on syndrome differentiation. ......
