ACCSAP Arrhythmias Exam UPDATED
QUESTIONS AND CORRECT ANSWERS
Paroxysmal Atrial Fibrillation - CORRECT ANSWER AF that terminates spontaneously or
with intervention within 7 days of onset
Persistent Atrial Fibrillation - CORRECT ANSWER Continuous AF that is sustained >7 days
Longstanding Persistent Atrial Fibrillation - CORRECT ANSWER Continuous AF of >12
months' duration
Permanent Atrial Fibrillation - CORRECT ANSWER Term used when there has been a joint
decision by the patient and clinician to cease further attempts to restore and/or maintain sinus rhythm
What is the treatment of inappropriate sinus tachycardia? - CORRECT ANSWER -Beta-
blockers
-Ivabridine (blocks the If "funny current" located in the sinoatrial node and drives the sinus rate)
-Radiofrequency ablation (last resort)
-Compression stockings, exercise program, volume expansion, fludrocortisone (useful, but are not
specific recommendations)
What is the mechanism of monomorphic VT? - CORRECT ANSWER -Most commonly due to
a re-entry mechanism around an infarcted scar tissue
-Less commonly, MVT is due to a single focus in patients without structural heart disease
What is the mechanism of RVOT VT? - CORRECT ANSWER Triggered activity that
encompasses both delayed and early afterdepolarization
What is the trigger for torsades de pointes in the setting of QT prolongation? - CORRECT
ANSWER Early afterdepolarizations
What is the mechanism of catecholaminergic polymorphic VT? - CORRECT
ANSWER Delayed afterdepolarizations
