Calcium Channel Blockers Flashcards
CCB do what for the heart?
relax and slow down the heart
with what conditions do you want to slow and relax the heart?
A, AA,AAA
Antihypertensive
AntiAnginal (decrease o2 demand)
AntiAtrialArrhythmia
CCB side effects
Headache
Hypotension ( hold is systolic is less than 100)
CCB end in…
-dipine
Also verapimil
cardizem(diltiazem) given cont IV drip
4 Cardiac Arrythmias
Normal Sinus Rhythm
Ventricular Fibrilation
Ventricular Tachy
Asystole
QRS depolarization equals
ventricular
P wave equals
atrial
NSR
p wave- QRS- T wave
peak of P wave equal distance to QRS
V-fib
no pattern
V-tach
sharp peaks with pattern
Asystole
flat line, lack of QRS
Saw tooth wave
flutter
chaotic
fibrilation
bizarre
Tachycardia
Periodic wide bizarre
PVCs (short run of v-tach)
non lethal arrhythmias
PVCs
low-moderate priority
moderate if:
6 or more PVC in a minute
more than 6 in a row
R on T (PVC falls on Twave)
Lethal arrhythmias
high priority
will kill within 8 minutes or less
Asystole & v-fib
low/no cardiac output (no pulse)-> no brain perfusion -> confusion and death
potentially lethal arrhythmias
v-tach
potentially lethal
Cardiac output present (pulse)
PVC & vtach treatment
Ventricular, Lidocaine or amiodarone
Supraventricular arrhythymia treatments
ABCDs
Adenocard (adenosine): fast IV push
Beta-blockers (-olol)
CCBs
Digitalis (digoxin), Lanoxin
v-fib & systole treatment
defib for vfib (defibrilate)
epinephrine (1st) and atropine (2nd) for asystole
