Basic EKG and Arrhythmia Tx Flashcards
SA node rate
60-100
AV node rate
40-60
Ventricles rate
20-40
Polarization
“ready” or
“resting” state
Depolarization
firing or contraction
Repolarization
return to resting state, relaxing after contraction
Cardiac Cell Types
- Myocardial cells - causes the muscle to contract
2. Pacemaker cells - specialized cells of the conduction system which generate and conduct the electrical impulses
“P” wave
atrial contraction
PRI
- SA node fires
- Atrial contraction
- Impulse movement to AV node
QRS
Ventricular contraction
T wave
Ventricular relaxation
Sinus Pause/Arrest Tx
Atropine/Isuprel IF SYMPTOMATIC
Sinus Bradycardia Tx
Atropine (if symptomatic), dopamine, epi gtt, pacemaker
Sinus Tachycardia Tx
identify cause and Rx, Dig
Premature Atrial Contraction Tx
Dig (if symptomatic), treat cause
Paroxsysmal Atrial Tachycardia Tx
- Vagal Maneuvers
- Adenocard
- Digoxin
- Verapamil
- Lopressor
- Synchronized Cardioversion
Atrial Fibrillation Tx
Dig if HR over 100
Junctional (Escape) Tx
Atropine (if symptomatic), Dopamine, Pacemaker
Premature Junctional Contractions Tx
Treat cause
