Implication

Should not yet change acute MI management; hypothesis-generating observation requires validation in larger cohorts.

Structured PICO

P
Population
5 patients who suffered an acute anterior myocardial infarction
O
Outcome
Electrocardiographic changes (transient giant R waves) and clinical course (ventricular fibrillation, development of nontransmural myocardial infarction)surrogate

Transient giant R waves in early acute anterior MI may indicate severe regional ischemia and high risk for ventricular fibrillation, though not necessarily massive transmural necrosis.
