Septal leads - Study guides, Class notes & Summaries

1. A pt present to the ED with complaints of chest pain. The 12-lead EKG reveals ST segment elevation in leads I and aVL. The initial BP is 112/69 and decreases to a systolic of 60 mmHg following a dose of nitroglycerin 0.4mg SL. The next most appropriate intervention is to: A. Complete a fibrinolytic check sheet B. Initiate a dopamine drip for blood pressure control C. Obtain a R sided EKG D. Administer a 0.9% NS bolus IV - D. Administer a 0.9% NS bolus IV Pts can be sensitive to va...

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...

The valve between the right atrium and right ventricle is named because it has _____. - answers-three cusps A small patch of tissue called the _____ acts as the pacemaker of the heart. - answers-sinoatrial node _____ samples the blood in each heart chamber for oxygen content and pressure. - answers-cardiac catheterization The simplest form of atherosclerosis is _____, which are thin, flat discolorations in the arteries that can enlarge and become thicker as they grow in length. - answer...

List some possible etiologies for pulmonary hypertension. Ans- An access of blood flowing through the pulmonary artery. Reduction in the caliber of the pulmonary vasculature (vasoconstriction) either: (A)Primaryunknown cause (B)Secondary- due to long-standing pulmonary congestion due to left heart failure. Why might there be a volume overload in the pulmonary arteries? Ans- This is usually due to a shunt, where blood flows directly from the left side of the heart to the right. This res...
