1. Anterior infarction: ST elevation, Leads V1, V2, V3, V4 with or without abnormal Q waves Usually associated with occlusion of the LAD branch of the LCA 2. Lateral infarction: ST elevation, Leads I, aVL, V5, V6 with or without abnormal Q waves May be a component of a multiple site infarction Usually associated with obstruction of Left circumflex artery 3. Inferior infarct: ST elevation, Leads II, III, aVF with or without abnormal Q wave Usually associated with RCA occlusion 4. Right Ven...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...

Foundations CBR20 – Cardiology Exam Questions With Answers 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 non-transmural infarctio...

Right ventricular infarction (RVI) lead changes - II, III, AVF R ventricular infarction s/s - clear breath sounds, hypotension, JVD. R ventricular dilation and dec contractility>> dec preload and CO Reperfusion therapy standard - Within 60 min of ED arrival Common causes of PEA - Hypoxia, tension pneumo, cardiac tamponade BNP as a marker - of L ventricular dysfunction bc ventricles make BNP and an inc of over 100 pg/ml indicates symptomatic HF Transcutaneous pacing (TCP) - ...

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...

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...
