Question 1

Péricardite : Nommer les 4 étapes de changement à l’ECG et la durée

Answer 1

Stages of Pericarditis
Pericarditis is classically associated with ECG changes that evolve through four stages.

Stage 1 – widespread STE and PR depression with reciprocal changes in aVR (occurs during the first two weeks)

Stage 2 – normalisation of ST changes; generalised T wave flattening (1 to 3 weeks)

Stage 3 – flattened T waves become inverted (3 to several weeks)

Stage 4 – ECG returns to normal (several weeks onwards)

NB. Less than 50% of patients progress through all four classical stages and evolution of changes may not follow this typical pattern.
