SAEM EMERGENCY MEDICINE EXAM
1. What are the top 3 causes of morbidity/mortality in acute chest pain? ANS
>>> ACS pulmonary embolism
aortic dissection
2. What is the cardioversion and defibrillation joules? ANS >>> cardioversion =
50-100 J defibrillation = 200 J

, 3. What is the most common EKG finding in a pulmonary embolus? What
rdia
should you be on the lookout for? ANS >>> most common = sinus tachyca
ave inversion
look for = "S1Q3T3" (large S wave in lead I + Q wave in lead 3 + T w
in lead 3) al alternans?
big and small
4. What should you worry about if a patient's EKG shows electric
What does this look like? ANS >>> cardiac tamponade! looks like
alternating spikes
5. Describe the basic evolution of the EKG of a patient having a STEMI ANS
>>> 1-nor- mal
2- T waves become wide and tall
3- ST elevation
4- Q waves and T wave inversion
5- Q waves persist but T wave normalizes
6. chest pain, weakness, nausea, fatigue
