Draw what a stemi looks like - correct answer What do we look for in a patient with atrial fibrillation and draw - correct answer No definitive p wave and irregular rate What do we look for in a patient with atrial flutter and draw - correct answer No definitive p wave Shark-tooth morphology, usually irregular but can be regular Draw monomorphic ventricular tachycardia - correct answer Only waves What are the normal intrinsic rates for the following: ___________ SA node ___________ AV junction ___________ Ventricles - correct answer 60-100 BPM 40-60 20-40 7. Label all the wave forms in the following image (P, Q, R, S, T): - correct answer ☑️ 7b. What is the approximate rate on the above rhythm 300, 150, 100, 75, 60, 50, 40, 30. SHOW YOUR WORK - correct answer 50bpm P, QRS and T waves are associated with what occurrence in the heart? (list all) - correct answer P- SA node fires, atria depolarize QRS- purkinje fibers create ventricular depolarization T- atria and ventricles repolarize List and explain three reasons we get an EKG - correct answer Rate- 60-100 bpm if regular Rhythm- is it regular or irregular (is the R to R normal) Are there any major blockages Explain 1 degree AV block, 2 Degree type 1 and 3 degree AV blocks - correct answer 1°- p-r interval is long 2°- wenkebach, p-r interval elongates to a dropped beat 3°- no p wave with every qrs, no relationship Describe asystole - correct answer No electrical activity Draw asystole - correct answer —————— 13.
