Detailed explanation-1: -What is an ST elevation myocardial infarction? The medical term for heart attack is myocardial infarction or MI. Some types of myocardial infarctions, or heart attacks, are caused by a partially blocked coronary artery. A heart attack with a completely blocked coronary artery is called a STEMI.
Detailed explanation-2: -Type 1 MI is due to acute coronary atherothrombotic myocardial injury with plaque rupture. Most patients with ST-segment elevation MI (STEMI) and many with non-ST-segment elevation MI (NSTEMI) comprise this category.
Detailed explanation-3: -ST depression occurs when the J point is displaced below baseline. Just like ST elevation, not all ST depression represents myocardial ischemia or an emergent condition. There are multiple conditions associated with ST depression. Some of these include hypokalemia, cardiac ischemia, and medications such as digitalis.
Detailed explanation-4: -Some of the other cardiovascular pathologies that depict ST-segment elevation in an electrocardiogram are as follows: pericarditis, myocarditis, right bundle branch block, stress cardiomyopathy (Takotsubo), early repolarization, acute vasospasm, and left ventricular hypertrophy [2, 4].
