ЭЛЕКТРОКАРДИОГРАФИЧЕСКИЕ СИНДРОМЫ

Abstract

Introduction. Sudden cardiac death (SCD) is a global health concern, often associated with specific clinical and electrocardiographic syndromes. While electrocardiography (ECG) is a crucial diagnostic tool in cardiology, it does not always provide a direct diagnosis or prediction of SCD. However, there are indirect criteria and syndromes that aid in diagnosing complex clinical cases in cardiology. Aim. This study aims to review various electrocardiographic syndromes known to predict sudden cardiac death, drawing from both domestic and foreign literature. Results. Wellens syndrome (WS) is an ECG pattern indicating a high risk of anterior wall myocardial infarction caused by anterior interventricular artery occlusion or critical stenosis. The de Winter pattern is an ECG sign associated with proximal LAD occlusion and the absence of ST segment elevation. Aslanger pattern is linked to coronary artery occlusion in patients with multivessel coronary artery disease, reflecting a combination of inferior MI and diffuse ischemia. Chaterrier's phenomenon (cardiac memory phenomenon) manifests as abnormal T wave inversion during normal sinus rhythm after myocardial electrical stimulation cessation.The Sgarbossa criteria aid in diagnosing acute myocardial infarction in patients with previous left bundle branch block. ECG signs of arrhythmogenic dysplasia of the right ventricle include negative T-waves in leads V1-V3 and an "epsilon" wave in lead V1, reflecting delayed depolarization of the right ventricle. Conclusion. Early recognition of these ECG patterns can aid in secondary prevention of AMI, fatal rhythm disturbances, and SCD, while also preventing overdiagnosis of myocardial ischemia in patients with implanted devices.
