1、窦性心率震荡的临床研究［摘要］日的：探讨急性心肌梗死患者和扩张型心肌病患者的室性心律失常Z后的窦性心率变化与预后关系。方法：检测40例急性心肌梗死患者组、25例扩张型心肌病患者组及50例冠心病非急性心肌梗死伴有室性早搏组(对照组)的室性心律失常之后的窦性心率变化［震荡初始(T0)、震荡斜率(TS)］、左室射血分数(LVEF)3项指标，并观察3项指标与1年内死亡发生率的关系。结果：①急性心肌梗死组震荡初始(T0)为(-0.38±2.34)%,震荡斜率(TS)为(2・30±1・10)ms/RR；扩张型心肌病组震荡初始为(-0.3
2、8+2.26)%,震荡斜率为(4.67±2.86)ms/RR；对照组震荡初始为(-2.26±3.16)%,震荡斜率为(8.60±6.84)ms/RR,3组比较差异冇统计学意义，P0.05；震荡斜率、LVEF比较差异有统计学意义，P0.05。④3组各指标与1年内的死亡发生率组间比较差异无统计学意义，P>0.05o结论：室性心律失常Z后窦性心率震荡不一定能预测死亡率，死亡率的高低在于该种疾病病变的严重程度。［关键词］窦性心率震荡；震荡初始；震荡斜率；预后；研究［中图分类号］R541.7+3［文献标识码］A［文章编号J1674-4
