2025/2026 Exam Questions and Answers
| 100% Solved
Brugada Syndrome - 🧠ANSWER ✔✔Common in SE Asia. Major cause of
death in young, Asian males. ST elevation in leads V1-V3. Appears like
RBBB in pericardial leads.
VT appears more like Torsades than Polymorphic VT (the latter of which is
often proceeded by long-short intervals or rate acceleration)
Ashman's Phenomon - 🧠ANSWER ✔✔Long, short beats. Often in AF but
not exclusively.
A predisposition to extort and aberration. A long interval precedes a short
one, and the ventricles are caught off guard, repolarizing as if they were
preparing for another long interval.

, Wendesky Effect - 🧠ANSWER ✔✔A prolonged lower threshold of
excitability induced by a strong stimulus. Explains why thresholds may
appear lower while decrementing opposed to incrementing
Wolf Parkinson White Syndrome - 🧠ANSWER ✔✔This is caused by the
presence of an abnormal accessory electrical conduction pathway between
the atria and the ventricles. Electrical signals traveling down this abnormal
pathway (known as the bundle of Kent) may stimulate the ventricles to
contract prematurely, resulting in a unique type of supraventricular
tachycardia referred to as an atrioventricular re-entrant tachycardia.
May present with a delta wave (extra wave at start of qrs)
Long QT Syndrome - 🧠ANSWER ✔✔QTc > 500ms, or a 25 % increase in
QT over baseline. Can be causes by Class I or III antiarrhythmics, or by low
Potassium. Cause of death in 10-15% of SIDS cases. ICD recommended.
Propensity for syncope, Torsades, and SCD.
Treat with beta blockers, Rate Smoothing to control EADs
