May aid early ECG recognition of inferior MI; supports further prospective validation before changing practice.

Is ST segment depression in lead aVL a sensitive marker for acute inferior myocardial infarction?
ST segment depression in lead aVL is a highly sensitive and sometimes the only early electrocardiographic marker for acute inferior myocardial infarction.
Birnbaum et al. (1993) conducted an observational in Acute inferior myocardial infarction (n=107). ST segment depression in aVL was evaluated on Prevalence of reciprocal ST depression in aVL. ST segment depression in aVL was present in 104 of 107 patients with evolving acute inferior myocardial infarction and was the sole early electrocardiographic sign in 7.5% of cases.
