摘要
目的探讨应用动态心电图(Holter)心率变异性(HRV)指标评价急性脑卒中患者心脏自主神经功能的价值。方法 96例于本院住院治疗的急性脑卒中(脑梗死59例和脑出血37例)患者设为观察组,选择96例同期本院非心脑血管病住院患者作为对照组,对比两组Holter记录仪24 h的动态监测结果。结果观察组的窦性R-R间期的标准差、窦性R-R间期平均值的标准差、窦性R-R间期的平方根及两个相邻R-R间期互差>50 ms的心跳数所占分析信息间期内心搏数的百分比均显著低于对照组(P<0.01),观察组的脑梗死与脑出血患者上述指标的差异均无统计学意义(P>0.05)。结论应用Holter的HRV指标评价急性脑卒中患者心脏自主神经功能,能预测急性脑卒中患者的病情变化及演变趋势,对防止心脏功能障碍加重、及时发现心脏并发症有重要意义。
Objective To explore the application of heart rate variability（HRV） indicator of dynamic electrocardiogram（Holter） in the evaluation of cardiac autonomic nervous function of the patients with acute cerebral apoplexy. Methods 96 cases of the patients with acute cerebral apoplexy hospitalized in our hospital（59 cases with cerebral infarction and 37 cases with cerebral hemorrhage） were set as Observation Group, and 96 cases with non-cardiocerebrovascular diseases hospitalized in this hospital during the corresponding period were selected as Control Group. 24 h dynamic monitoring results of Holter recorder of these two groups were compared. Results Observation Group was significantly lower than Control Group in terms of the percentage of heartbeats in the heart rate within information interval when standard deviation of sinus RR interval, standard deviation of average of sinus RR interval, square root of sinus RR interval and adjacent R-R interval was 〉50 ms（P〈0.01）; There was no statistical difference in above indicators between cerebral infarction patients and cerebral hemorrhage patients in Observation Group（P〉0.05）. Conclusion The application of Holter HRV indicator in the evaluation cardiac autonomic nervous function in the patients with acute cerebral apoplexy, can predict the conditions and evolution trend of the patients with acute cerebral apoplexy, and has important significance in preventing the aggravation of cardiac dysfunction and timely detecting cardiac complications.
