204例器质性心脏病后室性早搏患者不同中医证型心率变异性分析

目的 观察器质性心脏病后室性早搏患者不同一般情况、不同中医证型心率变异性情况.方法 对器质性心脏病后室性早搏患者进行中医辨证分型,统计分析不同性别、不同年龄段、不同证型患者心率变异性差异,判断临床预后.结果 204例器质性心脏病后室性早搏患者不同性别心率变异性比较无显著差异,不同年龄段心率变异性比较差异有统计学意义（P＜0.05）;痰湿阻滞证型与阴虚火旺证型心率变异性比较无显著差异（P＞0.05）,心气不足证型与瘀血内阻证型心率变异性比较无显著差异（P＞0.05）,痰湿阻滞证型、阴虚火旺证型与心气不足证型、瘀血内阻证型心率变异性比较差异有统计学意义（P＜0.05）、心阳不振证型与以上4种证型心率变异性比较差异有统计学意义（P＜0.05）.结论 器质性心脏病后室性早搏患者年龄越大,心率变异性数值越低,预后越差;5种中医证型中心气不足证型和瘀血内阻证型总体心率变异性数值最高,预后相对较好,心阳不振证型总体心率变异性数值最低,预后相对较差.

Analysis of Heart Rate Variability of Different TCM Syndrome Types in 204 Cases with Premature Ventricular Contractions of Organic Heart Disease

Objective： To investigate the heart rate variability of different TCM syndrome and different general conditions in patients with PVC of organic heart disease. Methods： According to the syndrome differentiation, the patients with PVC of organic heart disease were divided randomly into 2 groups. Some indicators were analyzed the heart rate variability differences among patients of different sex and age and TCM syndrome to judge the clinical prognosis. Results： There was no statistically significant difference of heart rate variability in patients of different sex,there was a statistically significant difference of heart rate variability in patients of different age;there was no statistically significant difference of heart rate variability between phlegm dampness stagnation and yin deficiency and fire excess, and between deficiency of heart-qi and stagnation of blood stasis. There was a statistically significant difference of heart rate variability in phlegm dampness stagnation yin deficiency and fire excess and deficiency of heart-qi and stagnation of blood stasis. There was a statistically significant difference of heart rate variability between flaccidity of the heart-yang and the other four TCM syndromes. Conclusion： Patients with PVC of organic heart disease,the older the age,the lower the measured values of the heart rate variability,the worse prognosis. The score of the heart rate variability of deficiency of heart-qi and stagnation of blood stasis was the highest, the prognosis was better, The score of the heart rate variability of deficiency of flaccidity of the heartyang was the lowest, the prognosis was worse.
