Electrocardiographic diagnosis of postinfarction regional pericarditis. Ancillary observations regarding the effect of reperfusion on the rapidity and amplitude of T wave inversion after acute myocardial infarction.

BACKGROUND The ECG recognition of diffuse pericarditis following acute myocardial infarction has been based on changes of the ST segment and, to a lesser extent, alterations of the PQ segment. No ECG criteria exist for the diagnosis of postinfarction regional pericarditis. Recently, it was observed that the T wave evolution follows an atypical pattern… CONTINUE READING
