Ventricular tachycardia & Ventricular fibrillation Flashcards
describe what ventricular tachycardia is
increased heart rate
what are the symptoms associated with ventricular tachycardia
dizziness, hypotension, palpitations, cardiac arrest
describe the ECG seen in ventricular tachycardia
wide QRS complexes, polymorphisms(TDP)- looks like mountains
what is the treatment for stable ventricular tachycardia
amiodarone(class III) + class I(e.g. lignocaine, aka lidocaine)
what is the treatment for unstable ventricular tachycardia
DCCV(direct current cardioversion)
what is the treatment for pulseless ventricular tachycardia
defibrillation
describe what ventricular fibrillation(VF) is
rapid irregular ventricular contractions with useless effect
describe the seriousness of VF
life threatening, cardiac arrest usually follows VF
what are the symptoms of VF
syncope, cardiac arrest
what is seen on the ECG for VF
wandering baseline, irregular, random wave forms, no identifiable QRS
what is the short term treatment given for VF
defibrillation and magnesium chloride
what is the long term treatment for VF
implantable cardioverter defibrillator(ICD)
