摘　　要：目的:探讨期前收缩后的T波异常对冠脉供血不足的诊断价值。方法:对2007年1月～2009年8月间收治的50例临床确诊的冠脉供血不足患者的临床资料进行回顾性分析。结果:50例患者经心电图检查,平静时心电图显示有早搏(室性或室上性),每次早搏代偿间歇后第～个窦性激动的T波倒置,即期前收缩后的T波异常,其中30例临床诊断为冠心病心绞痛。15例患者结合生化常规、心脏超声、心脏摄片检查分别诊断为心肌炎、心肌病、心肌肥厚。5例诊断为自主神经功能紊乱,未发现器质性心脏病变。最后经冠脉造影检查全部确诊为冠脉供血不足。结论:当患者有胸痛、胸闷、心前区压迫感等心肌缺血症状,心电图若有期前收缩后的T波异常,对冠脉供血不足有诊断价值。Objective：To study Period before the contraction of the T-wave abnormality on the diagnosis of coronary insufficiency. Methnds：Right in January 2007-August 2009 One hundred 50 cases of coronary insufficiency in patients with confirmed clinical data were analyzed retrospectively.Results：50 cases of patients by ECG examination,calm,electrocardiogram showed premature beats （ventricular or supraventricular）,each premature beat after a compensatory pause sinus excited T-wave inversion,after the immediate pre-contraction T-wave abnormalities,which 30 cases diagnosed as angina pectoris.15 patients with routine biochemistry, cardiac ultrasound,cardiac radiography examination were diagnosed as myocarditis,cardiumyopathy,cardiac hypertrophy.5 cases diagnosed as autonomic nerve dysfunction and found no organic heart attack. Finally check all diagnosed by coronary angiography for coronary insufficiency.Conclusion：When patients have chest pain,chest tightness,precordial oppressive symptoms such as myocardial ischemia,ECG period of pre-conlraction if T-wave abnormalities,right coronary insufficiency have diagnostic value.
