Transient pathological Q waves in suspected acute myocardial infarction: 'electrical stunning'.
In acute coronary syndromes the development of pathological Q waves is usually taken as evidence of established myocardial infarction (MI). We describe two patients with suspected acute MI who developed transient pathological Q waves. Cardiac enzymes were normal and cardiac catheterisation showed severe proximal coronary disease. Recognition of 'non-infarction' Q waves is important and may influence management of these patients.
