1、心率变异性及脾肾阳虚型慢性心力衰竭相关性探析［摘要］目的探讨心率变异性（HRV）与脾肾阳虚型慢性心力衰竭（CHF）的之间的关系及其意义，为脾肾阳虚型慢性心力衰竭中医证型的临床诊断，提供客观的心电图参数。方法将入选的120例慢性心力衰竭患者进行中医辨证分型,分为脾肾阳虚型与非脾肾阳虚型两组，并对两组患者进行24h动态心电图检查后，实施心率变异性长程时域分析，最后将两组进行比较。结果脾肾阳虚型慢性心力衰竭患者HRV各项指标的平均值为：SDNN（全部正常窦性心搏间期的标准差）为（67.25±17.56）ms、S
2、DANN（全程按5min分成连续的时间段，先计算每5分钟的NN间期平均值，再计算所有平均值的标准差）为（56.67±14.42）ms、SDNNindex（全程按5min分成连续的时间段,先计算每5分钟的NN间期标准差，再计算这些标准差的平均值）为（27.45±10.49）ms、rMSSD（全程相邻窦性心搏间期之差的均方根值）为（21.16±11.29）ms、pNN50（全部相邻正常RR间期之差>50ms的个数占总窦性心搏个数的百分比）为（6.53±5.52）%,与非脾肾阳虚型组患者比较，差异有高度统计学意
3、义（P<0.01）o结论心率变异性可以作为判定脾肾阳虚型心力衰竭患者心衰严重程度、指导治疗和判定预后的参考指标之一。［关键词］心率变异性；脾肾阳虚；心力衰竭［中图分类号］R541.6；R256.21［文献标识码］A［文章编号］1673-7210(2012)07(b)-0021-03CorreiationdiscussionofheartratevariabilityandyangdeficiencytypeofspleenandkidneywithchronicheartfailureXINGXiaobo
