COMPREHENSIVE QUESTIONS AND
ACCURATE SOLUTIONS
◉ if an SVT relies on autonomic tone to be induced, what is this
evidence of
Answer: -that the AVN is involved in the tachycardia (AVNRT, AVRT)
◉ What to give for catecholamine induced VT
Answer: beta blockers
◉ head vs tail of SN
Answer: head: fires off with sympathetic tone
tail: fires off with parasympathetic tone
◉ Brady-tachy syndrome
Answer: -Fibrosis of SAN is most common reason for SND
-this fibrosis can become diffuse and create substrate for AF/AFL
-this patient can be very slow with bouts of tachyarrhythmias like
AF/AFL
, -patients often most symptomatic to the long pauses after AF/AFL
termination due to fibrosis of SAN leading to exaggerated overdrive
suppression
-often spreads to distal conduction system as well (will cause
normal/slow V rates during tach)
◉ primary mechanism of SND
Answer: -decreased phase 4 slope leading to decreased automaticity
◉ Brugada syndrome EKG characteristics
Answer: -V1-V3 RBBB with ST elevation
◉ Brugada syndrome treatment
Answer: -ICD
-Quinidine can be given to patients experiencing a lot of shocks
◉ Most common cohort for Brugada
Answer: -southeast Asian males
◉ What causes Brugada
Answer: mutation in voltage gated Na+ channel gene
