摘要
对冠脉造影确诊冠心病而行经皮腔内冠状动脉成形术（PTCA）治疗的20例患者，采用心率变异性（HRV）频域法分析PTCA术球囊充气冠脉阻塞前、后患者的HRV，以评价PTCA米冠脉急性闭塞时心脏自主神经功能状况的变化，及与冠脉阻塞部位的关系。其中前降支组13例，右冠状动脉组7例。结果表明；PTCA术冠状动脉阻塞时前降支组HRV指标中的低频段（LFP）显著增高（267．36±21．30升至341．19±26．42bpm2／Hz，P＜0．05），说明HRV降低，右冠状动脉组的HRV虽有所增大，但未达统计学意义（P＞0．05）。提示PTCA术中HRV的变化可能与球囊扩张冠脉部位有关。
Heart rate variability (HRV) was analyzed in 20 Patients with coronary heart diseasewhich was diagnosised by coronary angiography. All patients underwent successful percutaneous translumi-nal coronary angioplasty (PTCA)' To evaluate the changes of autonomic nervous activity during coronaryaterial occlusion during PTCA, we measured the HRV in Patients be fore and during coronary occlu-sion. The results showed: the low frequency power (LFP) of HRV increased from 267. 36 ± 21. 30 to341. 19±26.42 bpm2/Hz (P<0. 05) during the left anterior descending (LAD) occlusion,but there wereno significantly change of HRV when right coronary artierial occluded. The results indicated that the raiseof sympathetic activity seems to be associated with the site of arterial occlusion.
