摘　　要：目的探讨早搏后的T波异常对冠脉供血不足的诊断价值。方法对2009年2月至2010年8月间收治的60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 60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一个窦性激动的T波倒置,即期前收缩后的T波异常,其中40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,心电图若有早搏后的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.Methods Right in February 2009 to August 2010,hundred 60 cases of coronary insufficiency in patients with confirmed clinical data were analyzed retrospectively.Results 60 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 40 cases diagnosed as angina pectoris.15 patients with routine biochemistry,cardiac ultrasound,cardiac radiography examination were diagnosed as myocarditis,cardiomyopathy,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-contraction if T-wave abnormalities,right coronary insufficiency have diagnostic value.
