Flashcards in Cardio I - Tachyarrhythmias Deck (17):
How are premature atria contractions treated if asymptomatic? Symptomatic?
Asymptomatic - no treatment
Symptomatic - Beta blocker
How are premature AV junctional beats treated?
What condition when coupled with premature ventricular contractions requires treatment? By what? If also has cardiac disease and is considered high risk?
AICD or amiodarone
What is "irregular irregularity" seen in?
What are the three types of A fib? How are each treated?
Paroxysmal - less than 7 days, terminates spontaneously
Persistent - greater than 7 days, cardiovert
Permanent - greater than 7 days, sinus rhythm not possible, rate control
What can appear to be atrial fibrillation but has regular ventricular rate?
Enlargening/changes in what chamber during atrial fibrillation are not conducive to cardioversion?
What are the three main goals/treatments for atrial fibrillation?
Correct underlying etiology
How fast is the flutter rate in atrial flutter? What is always treatment? What is the cure? What is used to prevent?
Rate control (BB, digoxin, CCA)
How are supraventricular tachycardias treated?
How are multifocal atrial tachycardias treated (correcting what two things)? What is a distinguishing factor?
Correct hypoxia and acidosis
3 or more consecutive different P-waves with rate > 100
What is the treatment for preexcitation? For nonparoxysmal junction tachycardia? What must not be done in the latter?
Localize and ablate
Override pacing, treat cause
Do not cardiovery
What is the preferred treatment for ventricular tachycardia? What else is sometimes used?
Rate control, override pacing
What distinguishes torsades de pointes from polymorphic ventricular tachycardia? How are each treated?
Torsades de pointes - prolonged QT - BB, magnesium, pacing
Polymorphic VT - normal QT - class I or III agent
Is there a treatment for accelerated idioventricular tachycardia? What is another name?
What is first line treatment for ventricular flutter/fibrilation?
