变异型心绞痛系由于冠状动脉痉挛、心肌供氧减少而引起的一组临床-心电图综合征。其典型临床表现为周期性反复发作的静息性心绞痛;其典型心电图改变为心绞痛发作时ST段呈一过性上抬伴有对应导联ST段压低,发作缓解后心电图恢复正常。1976年以来,我院共收治九例变异型心绞痛,其中一例在发作时心电图上出现暂时性异常Q波,发作缓解后异常Q波消失,随访年余,临床上未发现急性心肌梗塞的其它征象。鉴
Variant angina is a group of clinical-ECG syndromes caused by decreased coronary artery spasm and decreased myocardial oxygen supply. The typical clinical manifestations of recurrent recurrent recurrence of angina; its typical ECG changes in patients with angina pectoris ST segment showed a transient upturn accompanied by the corresponding lead ST segment depression, electrocardiogram returned to normal after the onset of remission. Since 1976, our hospital treated a total of nine cases of variant angina pectoris, one case of epilepsy in the onset of temporary abnormal Q wave, the onset of relief after the abnormal Q wave disappeared, more than follow-up, no clinical signs of acute myocardial infarction and other signs .
