What is the primary "high dose" dopamine causes vasoconstriction and
hemodynamic effect of:
(C) Increase afterload
Dopamine >10 mcg/kg/min
(A) Increase preload
(B) Decrease preload
(C) Increase afterload
(D) Decreased afterload
(E) Increase contractility
(D) Decrease contractility
Pulmonary HTN and cor pulmonale;
What causes the S3
sound?
Mitral, aortic, or tricuspid insufficiency
When are coronary during diastole
arteries perfused?
,What may you hear before S3 heart sound
crackles when a patient is
going into heart failure?
What is this called? Variant or Prinzmetal's Angina
Unstable angina with
transient ST segment
elevation
Can occur at rest or may
be cyclic (occurring at the
same time daily)
troponin negative
Can be precipitated by
nicotine, coke, or ETOH
There are changes in RCA, inferior LV
leads II, III, aVF....what type
of MI?
There are changes in LAD, anterior LV
leads V1, V3 V3, V4
There are changes in circumflex, lateral LV
leads V5, V6, I, aVL
There are changes in Low lateral LB
leads V5, V6
There are changes in high lateral LB
leads I aVL
There are changes in RCA, posterior LV
leads V1 and V2
There are changes in RCA, right ventricular infarct
leads V3R, V4R
, Marked ELEVATION of troponin/CK-MB: due to
miocardial stunning when vessel opens
What are some signs of
reperfusion arrhythmias: VT, Vfib, accelerated
reperfusion following
idioventricular rhythm (due to stunning)
fibrinolytic treatment of a
STEMI?
resolution of ST segment deviations
Chest pain relief
Your patient just had a contact the physician. Could be coronary artery re-
percutaneous coronary occlusion/stent thrombosis.
intervention (PCI)
(stenting) less than 24
hours ago:
He is experiencing
unrelenting chest pain, his
EKG shows ST elevation.
What should you do?
What could be
happening?
Your patient just had a retroperitoneal bleeding is most likely. Give
percutaneous coronary fluids/blood
intervention (PCI)
(stenting) less than 24
hours ago:
He is experiencing sudden
low severe back pain and
becomes hypotensive.
What is happening?
what is a normal ankle- >1 (get by dividing ankle pressure by brachial pressure
brachial index (ABI)? on the same side)
