Supports noninvasive infarct size estimation by praecordial mapping in anterior MI; leaves open impact on management or outcomes.
Does praecordial mapping of R/S ratio and Q waves correlate with the loss of electrically active myocardium and creatine kinase release in patients with acute anterior infarction?
Praecordial mapping of R/S ratio and Q waves is a noninvasive, repeatable technique that correlates with enzymatic infarct size and can identify the early loss of electrically active myocardium in acute anterior infarction.
