  1. Septal myocardial infarctions primarily involve the:
    left coronary artery
  2. The diagonal arteries of the left coronary arteries supply blood to the:
    anterilateral wall of the left ventricle

    I, aVL & or v5 & v6
  4. Which two drugs can affect preload in patients with right ventricular infarctions?
    morphine & nitroglycerin only
  5. Anterior MIs most often involve which artery?
    left coronary artery
  6. ST segment elevation in the face of an anteroseptal MI would involve elevation if 1mm or more in these leads:
    v1, v2, v3, v4
  7. The condition caused by inadequate cardiac output (pump failure) is called:
    cardiogenic shock
  8. ST elevation of 1mm or more in these leads is indicative of a posterior MI:
    There are no leads facing leads for posterior MI.
  9. The leads that are reciprocal leads for a posterior MI are:
    v1, v2, v3, v4

    anaerobic
  12. A drug that is a naturally occurring catecholamine & stimulates both alpha & beta receptor site is:
    epinehprine
  13. Drugs that can be given down the endotracheal tube include all of the following except:
    A) valium
    B) epinephrine
    C) narcan
    D) atropine
    A) valium
    (this multiple choice question has been scrambled)
  14. The half-life of epinephrine is 3 to 4 minutes; the half life of vasopressin is:
    10 to 20 minutes
  15. The generic name for intropin is:
    dopamaine
  16. Mr. Johnson came to the hospital within the hour after his heart attack started. You would expect to see what indication of acute MI on his EKG?
    ST segment elevation in the leads over the damaged area
  17. In a lateral wall MI, which coronary artery is occluded?
    Circumflex
  18. The MI in Figure 20 is
    extensive anterior (anterior-lateral)
  19. In Figure 21 there is evidence of
    inferior MI
  20. Mrs. Campho had a previous inferior MI about 20 years ago. What would you expect to see on her EKG that would be consistent with her hold inferior MI?
    significant Q wave in II, III & AVF
  21. The order in shich an MI progresses through "the tree I's" is:

    third-degree AV block
  23. The rhythm in Figure 18 is
    third-degree AV block
