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 investigate the diagnostic value of T wave abnormalities after coronary artery coronary artery insufficiency. Methods The clinical data of 60 patients with clinically diagnosed coronary insufficiency admitted from February 2009 to August 2010 were analyzed retrospectively. Results Sixty patients were examined by electrocardiogram and electrocardiogram at peacetime showed premature beats (ventricular or supraventricular). Each premature beat compensated for the first sinus twitch T wave inversion after intermittent intermittent, abnormal T wave after premenstrual contraction , Of which 40 cases of clinical diagnosis of angina pectoris. Fifteen patients were diagnosed with myocarditis, cardiomyopathy and cardiac hypertrophy by biochemical routine, echocardiography and cardiogram. Five cases were diagnosed as autonomic dysfunction and no organic heart disease was found. Finally, all confirmed by coronary angiography coronary insufficiency. Conclusion When patients have chest pain, chest tightness, cardiac pressure and other symptoms of myocardial ischemia, ECG abnormal T wave after premature beat, coronary insufficiency has diagnostic value.
