From Premature Ventricular Contractions Flashcards
What is V Tach
three or more PVC’s in a row
What drugs are used for PVC
caines and rones
beta blocker
sotalol
procainamide
Who gets PVC’s
Stimulants: Caffeine, alcohol, nicotine, aminophylline, epinephrine, isoproterenol
Digoxin
Electrolyte imbalances
Hypoxia
Fever
Disease states: MI, mitral valve prolapse, HF, CAD
What are the risks with PVC’s
HF from decreased CO and hypoxia
What is a unique symptom with PVC’s
you wont feel a pulse here and there
What should be assessed with PVC’s
Apical-radial pulse rate
Who gets V tach
MI CAD Electrolyte imbalances Cardiomyopathy Mitral valve prolapse Digitalis toxicity Central nervous system disorders
What are some symptoms of V tach
Hypotension
Pulmonary edema
Decreased cerebral blood flow
Cardiopulmonary arrest
If V tach is hemodynamically stable (they have a pulse) then we know what
we probably wont get MI’s because we have CO
If they have V tach without a pulse what should we do
start CPR and defibrillation
epinephrine if defib is unsuccessful
What is V Fib
Zero regular organized contractions
Who gets V fib
Acute MI, CAD, cardiomyopathy VF may occur during cardiac pacing or cardiac catheterization VF may occur with coronary reperfusion after fibrinolytic therapy Accidental electrical shock Hyperkalemia Hypoxia Acidosis Drug toxicity
What are the symptoms of V fib
Unresponsive, pulseless, and apneic state
What is the treatment of V fib
CPR and defib
What is the treatment for Asystole
use epinephrine first then defib
