Abstract:

The ST segment of the precordial lead in the De Winter electrocardiogram is not elevated, but is inclined upward and downward; it is not easy to attract attention from medical staff. Coronary angiography in such patients often shows subtotal occlusion or occlusion of the anterior descending branch or left main trunk, which is also the main basis for being considered as a high-risk electrocardiogram such as acute ST segment elevation myocardial infarction. In practice, it has been found that coronary artery lesions in such patients are not only related to the anterior descending branch or left main artery, but also to the circumflex branch and right coronary artery. However, we found that a patient's anterior wall lead De Winter electrocardiogram change was indeed caused by right coronary artery occlusion, and reported it for readers.

Key words:

Electrocardiogram, Subtotal coronary occlusion, De Winter electrocardiogram change

摘要：

De Winter心电图胸前导联ST段不抬高，而呈上斜型压低，不易引起医护人员重视，此类患者的冠脉造影往往存在前降支或左主干存在次全闭塞或闭塞，被认为是急性ST段抬高型心肌梗死等危症心电图的主要依据。实际工作中发现此类患者冠状动脉病变不只是前降支或左主干的病变，还有回旋支、右冠脉的病变。我们发现青岛大学附属威海市中心医院1例患者的前壁导联De Winter心电图改变，为右侧冠脉次全闭塞造成，现给以报道，以飨读者。
