• lopressor

Question 16

preexcitation syndrome

Answer 16

• WPW (delta wave, short PR)

- Accelerated transmission of impulses from atrium to ventricle via an accessory, bypass tract (bypassing the AV node)

Question 17

Question 18

we are concerned if there are more than ( ) PVCs/min

Answer 18

6, and there is structural damage, poor EF (<45), or ischemia.

Question 19

when to treat non-sustained Vtach

Answer 19

if structural defect or significant ischemia and EF <40%.

Question 20

how to treat non sustained Vtach

Answer 20

Lidocaine, procainamide and Amiodarone(live dose)

these block fast Na channels

Question 21

causes of sustained Vtach

Answer 21

ischemia (previous MI, pre-excitatory)

HOCM

Question 22

how to treat sustained Vtach?

Answer 22

if pt is stable think pharm first
***Amiodarone (2A) live dose
Cardioversion first if not hemodynamically stable= ACLS,
