摘　　要：目的观察高龄老年住院患者心律失常和心率变异性(HRV)。方法收集心内科住院75岁以上的老年患者121例,其中高血压病22例,冠心病51例,冠心病合并症19例,其他疾病及无器质性疾病患者为对照组(29例),分析其心律失常及HRV时域指标。结果高危室性早搏仅见于高血压病和冠心病患者。全部窦性心搏RR间期的标准差(SDNN)和HRV三角指数以冠心病合并症和高危室性早搏患者降低最显著,三角指数男性明显低于女性。结论高龄冠心病患者易发生高危室性早搏和HRV降低。Objective To observe the arrhythmia and heart rate variability（HRV） in advanced aged inpatients.Methods The arrhythmia and time domain indexes of HRV were analyzed in 121 inpatients aged 75 or more including 22 hypertensions,51 coronary heart diseases（CHD）,19 complications of CHD,and 29 controls in the department of cardiovascular diseases.Results High risk premature ventricular contraction（PVC） only occurred in patients with hypertension and CHD.Standard deviation of all normal-to-normal intervals（SDNN） and triangular index of HRV decreased significantly in patients with complications of CHD and high risk PVC,but triangular index in male patients was lower than that in female ones.Conclusion The advanced aged patients with CHD are more susceptible to high risk PVC and reduction of HRV indexes.
