对有致命性心律失常史的冠脉病变患者的HRV进行频域分析,以揭示心率自主神经控制与自发及诱发性室性心律失常的关系。 方法 54例冠脉病变患者,男48例,女6例,年龄61±8岁,其中25例曾有持续性室速(≥30s),29例曾有心脏静止。44例有心肌梗塞病史。用24h Holter记录、程序电刺激、血管造影及HRV分析方法进行研究。HRV频域用自相关方法计算。总功率
Frequency domain analysis of HRV in patients with coronary artery disease with a history of fatal arrhythmias revealed the relationship between autonomic control of the heart rate and spontaneous and induced ventricular arrhythmias. Methods 54 patients with coronary artery disease, 48 males and 6 females, aged 61 ± 8 years, of whom 25 had sustained ventricular tachycardia (≥ 30s), 29 had cardiac rest. 44 patients had a history of myocardial infarction. Holter 24h recording, program electrical stimulation, angiography and HRV analysis methods were studied. The HRV frequency domain is calculated using the autocorrelation method. Total power
