Telemetry with pictures 25 Questions with Verified Answers
normal sinus rhythm - CORRECT ANSWER - normal intervals
- rate 60-100
- walks out
sinus bradycardia - CORRECT ANSWER - SA node in control
- rate <60
- normal intervals
- walks out
- treat with atropine IV push
sinus tachycardia - CORRECT ANSWER - SA node in control
- rate >100
- normal intervals
- walks out
- treat with vagal maneuvers, BBs, or CCBs
atrial fibrillation - CORRECT ANSWER - SA node not in control
- random ectopic foci cells firing in atria
- rate determined by AV node
- rate often high (RVR) up to 180s
- does not walk out
- no definable P wave
- normal QRS from AV node
- treat with amiodarone or cardizem
- treat with cardioversion and shock on R wave
- treat with anticoagulants
atrial flutter - CORRECT ANSWER - SA node not in control
- one random ectopic foci cell firing in atria
- rate determined by AV node
- saw tooth pattern
- does not walk out
- easily definable P wave
- same treatment as a fib
supraventricular tachycardia - CORRECT ANSWER - SA node not in control
- one cell rapidly firing
- AV node determines rate
- QRS narrow or wide
- may look like sinus tach
- treat with adenosine (reset drug), BBs, or CCBs
junctional rhythm - CORRECT ANSWER - AV node in control
- rate 40-60
- inverted or no P wave
- walks out
- treat with atropine to increase HR or an external pacemaker through femoral artery
accelerated junctional rhythm - CORRECT ANSWER - AV node in control and fires spontaneously
- no P wave
- faster than normal
- rate >60
- walks out
- treat with external pacemaker
first degree heart block - CORRECT ANSWER - slow electrical conduction through atria
- PR interval >0.20 (up to 0.24)
- QRS and QT intervals normal
- rate can be slow or normal
- no symptoms or treatment
second degree heart block type 1 - CORRECT ANSWER - slow conduction between SA and AV node
- PR gets progressively longer until a QRS is dropped
- longer, longer till they drop that's how you know it's a Wenckebach
- P with no QRS
second degree heart block type 2 - CORRECT ANSWER - slow conduction between SA and AV node
- PR prolonged but remains consistent until a QRS is dropped
- same, same, drop
- 2 normal heart beats, then a QRS drop
- leads to 3rd degree heart block
- treat with atropine
third degree heart block - CORRECT ANSWER - no longer rhythmic
- no relationship with SA and AV node
- P wave buried into QRS but both walk out
- HR low in 20-30s
- only treatment is a permanent pacemaker
- medical emergency
bundle branch block - CORRECT ANSWER - delayed conduction in ventricle instead of atria
- wide QRS complex
- can be left or right
- common in elderly
- don't treat, just monitor
premature atrial contraction - CORRECT ANSWER - SA node fires prematurely
- looks like an early beat
premature ventricular contraction - CORRECT ANSWER - an ectopic foci in the ventricle fires, causing contraction
- looks like QRS without a P wave
- can be from one or many cells (unifocal or multifocal)
- treat with BBs or CCBs
- can be caused from potassium imbalances, HTN, drugs, caffeine, stress, hypoxia, or MI
bigeminy - CORRECT ANSWER - a pattern of PVCs
- PVCs every second beat
- poor perfusion because PVCs don't push good amount of blood out
- beat, PVC, beat, PVC
trigeminy - CORRECT ANSWER - PVCs occurring every third beat
- still not a good beat
atrial pacemaker - CORRECT ANSWER - pacemaker working as the SA node
- spike before a P wave
ventricular pacemaker - CORRECT ANSWER - pacemaker working as the AV node
- line before QRS complex
- P wave can be present
atrioventricular pacemaker - CORRECT ANSWER - pacemaker works as both the SA and AV nodes
- looks like a line before P and QRS waves
ventricular tachycardia - CORRECT ANSWER - neither SA node or AV node are controlling heart
- one ectopic foci firing in ventricles
- looks like constant PVCs
- a run of 3 or more PVCs
- treat Hs and Ts
- if pulse, treat with amiodarone
- if no pulse, CPR or defibrillation or epinephrine or vasopressin
ventricular fibrillation - CORRECT ANSWER - SA and AV node not in control
- multiple ectopic foci firing in ventricle
- treat with CPR or defibrillation in the first 2-3 minutes or epinephrine, vasopressin, or amiodarone
torsades - CORRECT ANSWER - specific form of VTACH but twists and looks like a combination of VTACH and VFIB
- can lead to VFIB
- does not look uniform
- treat with magnesium
asystole - CORRECT ANSWER - flatline
- no electrical activity
- treat with CPR or epinephrine
pulseless electrical activity - CORRECT ANSWER - heart not actually pumping
- leftover electricity in heart makes it look like a beat, but no pulse
- can look junctional
