目的探讨高血压患者左室质量指数(LVMI)与心率变异性的相互关系。方法按性别将2001年1月至2005年12月在荆州市公安卫生学校附属医院就诊的125例高血压患者分为两组,测算两组的左室质量指数和心率变异性时域分析指标,计算其相关系数。结果 LVMI 与24 h 内全部正常 RR 间期的标准差(SDNN)、24 h 内连续每5 min RR 间期平均值的标准差(SDANN)、24 h 内相邻正常心搏 RR 间期差值的均方根(rMSSD)的相关系数男性分别为-0.74、-0.61、-0.59;女性分别为-0.65、-0.68、-0.73。P 值均<0.05,差异有显著性意义。结论高血压患者的左室质量指数与心率变异性呈负相关。
Objective To investigate the relationship between left ventricular mass index (LVMI) and heart rate variability in hypertensive patients. Methods One hundred and twenty-five hypertensive patients treated in the affiliated hospital of Jingzhou Public Security School from January 2001 to December 2005 were divided into two groups according to gender. The time-domain analysis indexes of left ventricular mass index and heart rate variability were calculated. Calculate the correlation coefficient. Results The standard deviation (SDNN) of all normal RR intervals within 24 h and the mean standard deviation (SDANN) of RR intervals between consecutive LVMIs within 24 h, RRD interval between adjacent normal hearts within 24 h (RMSSD) were -0.74, -0.61, -0.59 respectively for males and -0.65, -0.68, -0.73 for females respectively. P values were <0.05, the difference was significant. Conclusion There is a negative correlation between left ventricular mass index and heart rate variability in hypertensive patients.
