This document contains a collection of ECG quiz cases from a Gulf and Saudi conference in 2013, with the diagnosis and recommended treatment provided for each case. The cases cover various arrhythmias and conditions including WPW syndrome, long QT syndrome, catecholaminergic polymorphic ventricular tachycardia, Brugada syndrome, short QT syndrome, pacemaker-induced cardiomyopathy, pericarditis, early repolarization, arrhythmogenic right ventricular dysplasia, and anterior myocardial infarction. The document provides brief guidance on diagnosis, evaluation, and management for each ECG case.

1. ECG Quiz from Gulf and Saudi

(Attended the conference)
Answer follows each ECG

3. • WPWs
• Right posterior
• EPS to ablate

6. • Long QT
• Start BB

8. • EP study, if sustained V tach. is inducible
implant ICD. If not inducible give amiodarone.

10. • Catecholaminergic arrhythmia. Start Beta
blockers and amiodarone.
• ICD in this 13 y boy is second option.

12. • Short QT with high take off, incomplete RBB.
• Leave him alone, no intervention or drugs.
• Short QT is said to be present if QT is < 360 ms

14. • Pacemaker induced cardiomyopathy
• Upgrade to CRT

16. • Brugada syndrome
• ICD is the prober management.

18. • High take-off (LII), short QT
• ICD is indicated

20. • Short QT
• Start amiodarone.

22. • The answer is evident, the lead is broken and
induces inappropriate shocks. Immediately
magnet is put on the ICD to stop its function
till lead is changed.
• ICD Lead fracture is one of the causes of
inappropriate shocks. Other causes as
pacemaker program misinterpret sinus
tachycardia or AF as VT

24. • Recording from ICD memory prove that there
was no VF and the shock was given
inappropriately.

26. • The diagnosis is pericarditis: evidence is
diffuse ST elevation, PR depressed.
• Start high dose of aspirin and follow up.

28. • Brugada syndrome
• ICD is mandatory as he got VF

30. • Early repolarization.
• No intervention or evaluation.

32. • Long QT
• Non of the above.

34. • Arrhythmogenic RV dysplasia, notice the
epsilon wave in V1.
• Ablation of arrhythmogenic focus in RV
outflow is needed. Recurrence is expected and
redo ablation is to be done.

36. • Extensive anterior MI
