title: Myocardial infarction.
abstract: When a diagnosis of infarction or ischemia is considered, the diagnostic value is greatly amplified by comparison of serial ECGs, particularly when at least one is recorded during chest pain and another immediately after a therapeutic maneuver. Daily evaluation of serial ECGs, with a consistent standardization technique and lead placement, is essential to determine the evolution of MI and to evaluate changes indicating that new cardiac regions might be jeopardized by acute ischemia.
