From a study of 526 patients having automatic ECG analysis, criteria were established which diagnosed acute evolving Q wave myocardial infarction with 71% sensitivity and 98% specificity. Specificity was 100% when patients with known previous Q wave infarction were excluded. In pre‐hospital practice the high sensitivity and specificity were maintained. This method appears appropriate, when other criteria are met, for paramedic‐initiated pre‐hospital thrombolysis with remote supervision of a cardiologist by telephone. (Aust NZ J Med 1992; 22: 9–13.)
