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.
