| 摘 要： | 目的探讨冠状动脉慢血流(CSFP)患者在运动负荷实验后3min内的心率恢复(HRR)变化及意义。方法选取42例CSFP患者(CSFP组)及26名健康者(对照组),均进行心电图运动负荷试验,记录静息心率、峰值心率及运动后3min内的心率,计算运动停止后1、2、3min时的心率与运动中峰值心率的绝对差值(分别为HRR1、HRR2、HRR3),及心率恢复的校正值(HRR1%、HRR2%、HRR3%)。结果两组间静息心率、峰值心率、心率储备、预测储备心率、HRR2、HRR2%、HRR3、HRR3%及代谢当量(METs)、运动时间的差异均无统计学意义(P值均>0.05)。CSFP组的HRR1、HRR1%均显著低于对照组(P值均<0.01)。结论 CSFP患者HRR较健康者降低,推测此类患者存在自主神经调节异常的早期改变。

| Abstract: | Objective To investigate the changes and significance of heart rate recovery(HRR) in patients with slow coronary flow phenomenon(CSFP) in 3 min after maximal treadmill exercise testing.Methods A total of 42 patients with CSFP and 26 healthy individuals received treadmill exercise testing.Echocardiography was performed to measure their heart rate(HR) at rest,at maximum exercise and at 1,2,and 3 minutes after exercise.The percent recovery of HRR at 1,2,and 3 minute(HRR1%,HRR2%,HRR3%) were calculated and compa... |
