摘　　要：本文探讨了37例脑卒中患者HRV变化,发现脑卒中者与正常人比较SDANN下降,而RMSSD、PNN50无变化,说明脑卒中使交感张力增高,而对迷走张力影响较小。冠心病者与此不同。交感张力增高,迷走张力下降。脑卒中主要影响超低频HRV,并初步探讨了其变化的机理。There are a number of reports about heart rate varibflity (HRV) in myocaredial infarction. In generals, mailer the HRV, greater the mortality in acute period of myocardial infarction. Cardiovascular motorium is located in brain. Cerebropathia may affect HRV. This study is to identify the hypothes is whether HRV changes in cerebral crisis. 37Pts with cerebral infarction or hemorrahge (male 25, female 12, average age 68.8±9.4 years), 100 Pis with coronary heart disease (CAD) (Male61, female 39, average age 63.4±9.3 years). 19 health participants (male 7, female 12, average age 48.5±13.7 years) were divided into group A, B and C respectively. SDANN, RMSSD, PNN50 were measured by 24 hour Holter ECG. Results: SDANN of group A (68.2±25.3ms) and group B (82.2±26.4ms) were greater than that of group C (117.3±23.1ms) (P<0.005). There were no difference between group A (23.1± 14.8ms, 5.1±10.7%) and group C (21.1±10.7ms, 7.5±6.9%) in RMSSD and pNN50 (P>0.2). Significant difference existed in RMSSD and PNN50 between group B (21.1±10.7ms 3.7±7.1%) and C (P<0.05). SDANN of group B (82.2±10.7ms) was greater than that of group A. RMSSD and pNN50 of group A was not different from group B (P>0.05). Conclusions: (1) Cerebral crisis indeed HRV. (2) Effects of cerebral crisis on HRV is different from CAD, cerebral crisis mainly affects ultralow-frequency HRV, that is sympathetic tone increasement, no effect on parasympathetic tone. (3) Sympathetic tone increased and parasympathetic tone decreased in CAD.
