ECG signs of anterior myocardial infarction show significant recovery over one year, particularly in patients with smaller infarcts and lower initial heart rates.
ECG recovery on mapping may signal viable myocardium post-MI; leaves open its added value for risk stratification.
The recovery of the ECG signs of anterior myocardial infarction has been studied in 70 patients. A significant increase in R-wave amplitude and decrease in Q-wave amplitude on 24-lead precordial mapping was observed during one year after infarction. Patients with lower initial heart rate showed a greater recovery of R- and Q-wave amplitudes, as did patients with smaller infarcts, as assessed by peak heat-stable lactate dehydrogenase (LDH).
