A 48-year-old male presented with chest pain. His ECG (ECG 23.2) is shown on page 10.
a) List the abnormal ECG findings. (15% marks)
b) List two likely differential diagnoses consistent with these ECG finidngs. (10% marks)
c) Explain how to differentiate these two differential diagnoses using ECG criteria. (20% marks)
Not available.
The college answer and ECG image were both not available at the time of writing, so it is impossible to accurately reconstruct the original ECG, but judging from the question, it would have to have been either a question about Brugada criteria or Sgarbossa criteria. Seeing as the differentials generated by the application of Sgarbossa criteria are boring (they're infarcting, or they're not infarcting), the author settled on Brugada. The ECG is an example of VT from the LITFL page on broad complex tachycardias (example 2, to be precise).
So,
a) Major abnormalities:
b) Two differentials:
c) how to differentiate these two differential diagnoses using ECG criteria:
