Basic EKG and Arrhythmia Tx Flashcards
1
Q
SA node rate
A
60-100
2
Q
AV node rate
A
40-60
3
Q
Ventricles rate
A
20-40
4
Q
Polarization
A
“ready” or
“resting” state
5
Q
Depolarization
A
firing or contraction
6
Q
Repolarization
A
return to resting state, relaxing after contraction
7
Q
Cardiac Cell Types
A
- Myocardial cells - causes the muscle to contract
2. Pacemaker cells - specialized cells of the conduction system which generate and conduct the electrical impulses
8
Q
“P” wave
A
atrial contraction
9
Q
PRI
A
- SA node fires
- Atrial contraction
- Impulse movement to AV node
10
Q
QRS
A
Ventricular contraction
11
Q
T wave
A
Ventricular relaxation
12
Q
Sinus Pause/Arrest Tx
A
Atropine/Isuprel IF SYMPTOMATIC
13
Q
Sinus Bradycardia Tx
A
Atropine (if symptomatic), dopamine, epi gtt, pacemaker
14
Q
Sinus Tachycardia Tx
A
identify cause and Rx, Dig
15
Q
Premature Atrial Contraction Tx
A
Dig (if symptomatic), treat cause
