FoEM CBR22- Cardiology Exam What underlying pathologic process distinguishes myocardial infarction from angina/unstable angina? Atherosclerotic plaque rupture → exposed endothelium → clot attaches → reduced blood flow; if cell death occurs (usually due to complete vascular obstruction) then positive trop and MI; if no cell death occurs then negative trop and angina/unstable angina. What is the difference between transmural and nontransmural infarction? Transmural: usually STEMI, la...

Electrocardiogram (ECG) correct answer: Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) correct answer: Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? correct answer: Only monitors Straight line when machine is turned on but not connected to the patient correct answer: Isoelectric = no current ...
