摘要(Abstract)：
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。
