Analysis of the prevalence of ventricular late potentials in late post-acute myocardial infarction period based on the damaged wall

The analysis of the ventricular late potentials (VLP) has been considered a valuable diagnostic tool for stratification of patients at risk of life threatening arrhythmia. This study evaluates the prevalence of VLP in a late phase post-myocardial infarction (median 924 days) in patients with anterior/antero-lateral and inferior/inferodorsal wall lesion, from the data bank of BDECG AR, of State University of Rio de Janeiro General Hospital, Rio de Janeiro, Brazil, and test diagnostic performance of filters for VLP analysis. The results indicate that the prevalence of VLP is higher in inferior/infero-dorsal than anterior/anteroseptal wall infarction, and depends on filter setting.
