ventricular Flashcards
are p waves present in a PVC
no
describe QRS in PVC
widened
causes of PVCs
ischemia
electrolytes
hypoxia
caffeine
stress
treatment of PVCs
not all require
if they complain of palpitations…
-beta blockers, amiodarone
-treat underlying condition
-oxygen
what kind of PVC only occurs once
unifocal
multifical PVCs
happen several times, not regualrly
PVC occurs every other beat
ventricular bigeminy
PVC occurs every third beat
ventricular trigeminy
when PVCs occur so early that they fall on the T wave of preceding beat
R on T phenomenon
why is R on T dangerous
cardiac cells have not repolarized
PVCs that occur in pairs
couplets
PVC occurs between 2 regular complexes, does not interfere with regular cycle
interpolated PVC
does v tach have pulse
maybe … maybe not
ventricular rate of v tach
150-250
describe p waves and QRS in v tach
no P, wide QRS
causes of v tach
hypoxia
MI
electrolytes
meds
stimulants
stress
treatment of v tach
treat cause
amiodarone, lidocaine
cardiovert if pulse
defibrillate if pulseless
does v fib have pulse
no
ventricular rate of v fib
> 250
P/QRS in vfib
no P
no QRS, looks like static
causes of v fib
meds (Stimulants)
hypoxia
MI
caffeine
stress
electrolyte
treatment of vfib
DEFIBRILLATE
CPR
meds (epi, vasopressin, amiodarone, lidocaine)
oxygen (ETT placed)
is there a pulse in pulselessness electrical activity (PEA)?
no
what does EKG look like in PEA
weak, low amplitude, slow, regular, same in each lead
