KAISER EKG REVIEW TIPS QUESTIONS AND
ANSWERS SET A+
✔✔Paroxysmal SVT - ✔✔>150 bpm, Occurs with no warning lasting a brief period of
time and is self terminating
✔✔txt for stable SVT - ✔✔Vagal maneuvers, adenosine
✔✔txt for unstable SVT - ✔✔Synchronized cardiovert
✔✔what happens to p waves in junctional rhythms - ✔✔flat or inverted
✔✔junctional rhythm rate - ✔✔40-60
✔✔accelerated junctional rhythm rate - ✔✔>60
✔✔1st degree block - ✔✔PR interval >0.20 or 5 boxes
✔✔2nd degree av block type 1 - ✔✔wenckebach- longer and longer pr intervals
followed by a drop
✔✔2nd degree av block type 2 - ✔✔regular p waves, regular pr, then sudden drop of
qrs
✔✔3rd degree av block - ✔✔P wave independent of QRS, wide qrs, hr 20-40
✔✔Mobitz type 2 - ✔✔same as 2nd degree block type 2
✔✔2:1 conduction in 2nd degree block type 2 - ✔✔twice as many p waves than QRS
complexes
, ✔✔is mobitz I or II more serious - ✔✔II is more serious and can cause 3rd degree av
block
✔✔txt for second degree block type 1 - ✔✔observe, if symptomatic atropine,
epinephrine or temporary pacemaker
✔✔txt for second degree block type II - ✔✔observe for hemodynamic compromise, may
need atropine, epinephrine or dopamine, transucataneous pacemaker
✔✔is a second degree type 1 or 2 of more concern - ✔✔second degree type 2 is more
concerning because it is more unpredictable and may progress to third degree AV block
✔✔Which block has wide QRS and p and QRS do not match - ✔✔type 3
✔✔which block has regular intervals but drops a qrs - ✔✔2nd degree type 2
✔✔which block has increasing PR intervals - ✔✔2nd degree type 1
✔✔which block has a normal rhythm but pr interval longer than .20 - ✔✔1st degree
✔✔what block has rabbit ears or two r waves - ✔✔right bundle branch block
✔✔what block shows a deep slurred s wave in lateral leads - ✔✔right bundle branch
block
✔✔bigeminy - ✔✔pvc that occurs every second beat
✔✔trigeminy - ✔✔pvc that occurs every third beat
✔✔quadrigeminy - ✔✔pvc that occurs every 4th beat
✔✔couplet - ✔✔two pvcs occur together
✔✔unifocal pvc - ✔✔all PVCs look the same
✔✔multifocal pvc - ✔✔varied shapes and forms of the PVCs, suggesting more than one
irritable focus
✔✔txt for pvc - ✔✔txt underlying cause: correct hypoxemia, correct low potassium or
mag. can use amiodarone, lidocaine, pronestyl
✔✔monomorphic vtach - ✔✔all look the same
