CCBs, Cardiac Rhythms etc Flashcards
CCBS are like _____ for the heart
Valium
They have negative Chrono, Dromo., and Inotropic effects
Inotropic effect, Chronotropic, dromotropic
Ino-> contraction force
Chrono-> rate
Dromo -> Speed
Negative Inotropic effect, Chronotropic, dromotropic
- Decreased force
-Decreased rate
-decreased speed
Positive Inotropic effect, Chronotropic, dromotropic
- Increased force -> improved CO
- Accelerated HR
- Increased speed impulse
What conditions do you want to relax and slow the heart?
HTN
Angina
arrythmias
Common SE of CCBs
Headache and hypotension
Most CCBs end in
dipine” with exception to Diltiazem and verapilmil
Parameters for CCBs
Hold if SBP<100
Equally distant
- has a P wave, QRS, T wave with every waveform
Normal SR
No pattern, chaotic waveform
V- fib
Sharp peaks with a wave
Bizarre QRS
V-tach
Flat line
Aystole
Chaotic P waves
A-fib
Periodic Wide Bizarre QRS Complexes
PVCs
Saw tooth P-waves
Atrial Flutter
If it deals with QRS
If it deals with p Waves
its ventricular
Its Atrial
PVCs are usually low priority but are raised to a moderate priority when either one of 3 things happen:
- There are more than 6 PVCs in a minute
- More than 6 PVCs in a row
- A PVC falls on a T wave
Are PVCs after an MI good or bad
Good indicates heart is perfusing
What arrythmias are lethal and have highest priority
Asystole and V-Fib
This arrythmia has the potential to become lethal and must be quickly treated
V-tach
Treatment for PVCs and V-Tach
Lidocaine
and Amioderone
Tx for Supraventricular Tachycardia and atrial arrythmias
“ABCD”
A- Adenosine fast IV push less than 8 secs and 20mL flush of NS)
B- Beta Blockers
C-CCBs
D-Digitalis and Lanoxin
