CCB, C-tube & CHD Flashcards
CCB are like Valium for the heart
If in shock give CCB
If tachycardia give CCB
Shock No
Tachycardia Yes
CCB have a (negative / positive) inotropic, chronotropic, dromotropic effect
CCB have a negative inotropic, chronotropic, dromotropic
Negative inotrophic:
Negative chronotrophy:
Negative dromotrophy:
decrease speed that impulses from SA node travel to AV node (decrease conduction velocity)
weaken the myocardial contraction
decrease rate of impulse formation at SA node -> decelerate HR
Negative inotrophic: weaken the myocardial contraction
Negative chronotrophy: decrease rate of impulse formation at SA node -> decelerate HR
Negative dromotrophy: decrease speed that impulses from SA node travel to AV node (decrease conduction velocity)
What do CCB treat
A, AA, AAA
A: Antihypertensive-> Lower BP
AA: AntiAnginal - relax heart, works by decreasing oxygen demand
AAA: AntiAtrialArythmia: treats atrial-flutter / Fibrillation, premature atrial contraction, atrial bigeminy, SVT
Side effects of CCB
H.H.
Headaches - vasodilation
Hypotension- it relaxes BV
-Dipine is the ending of CCB
There are 2 more you have to remember by name
Verapamil (isoptin)
Cardizem (diltiazem) - can be given with an IV drip
Monitor BP before giving CCB
hold when
If SBP <100
If SBP <100 when Cardizem (diltiazem) is given with drip, titrate the rate of the IV depending on how low the SBP is

Pattern
Rhythm Strips Must Know by Sight
Asystole
Flat line
Asystole occurs when the heart’s electrical system fails, causing the heart to stop pumping. It can be a fatal arrhythmia
if it occurs in relation to a severe underlying illness
QRS wave will always be (Arterial / Ventricular)
Ventricular
“P” wave will always be about (Arterial/ Ventricular)
Arterial
Unless it’s a Lack of P wave then it’s ventricular
Lack of a QRS line is called
Asystole
Described as “SawTooth” is always…
Flutter
Chaotic is always the word to describe
Fibrillation
“Bizarre” is always the way the will describe
Tachycardia
More than 6 PVC in 1 minute
More than 6 PVC in a row
PVC Falls on T wave of pervious beat
What is the priority level
Moderate
If its only PVC wave, then it is a low level
PVCs, or premature ventricular contractions, are extra heartbeats
They are a common type of irregular heartbeat (arrhythmia)
Premature ventricular contractions (PVCs) are
extra heartbeats begin Ventricles
Disrupt the regular heart rhythm, fluttering / Skipped beat
Is PVC after MI a major concern
No, it is a good sign.
It means they are reprofusing
Asystole & Vfib both share (no /low / high) Cardiac output
What can happen to a patient with these conditions
No cardiac output
Leathal within 8 minutes
VTACH has this level of seriousness
Potentially fatal
For Vtach problems this medicine
amiodarone
Lidocaine (in the Past)
Artial/ Supra ventricular
Use these types of medications
A,B,C,D
Adenocard (Push <8sec) - (can go into Asystole for 30 sec)
Beta Blockers (lol) - (Same as CCB)
slow heart down
SE: Head / Hypotension
CCB:
Digitalis ( Lanoxin / Digox)
