As a domain expert in cardiology, I can provide you with a detailed explanation of ST elevation. Definition: ST elevation refers to a specific pattern seen on an electrocardiogram (ECG) that is indicative of acute myocardial injury. It is characterized by an elevation of the ST segment by greater than 1 mm (0.1 mV) in two or more contiguous precordial leads or two or more adjacent limb leads. This finding is often associated with conditions such as acute coronary syndrome, particularly **ST-segment elevation myocardial infarction (STEMI)**, which is a type of heart attack caused by a complete blockage of a coronary artery. Additionally, the presence of a new or presumed new left bundle branch block (LBBB) can also mimic the appearance of ST elevation and is considered significant in the context of possible myocardial infarction. read more >> -
