[Value of myocardial scar in predicting malignant ventricular arrhythmia in patients with chronic myocardial infarction].

Objective: To assess the predictive value of myocardial scar mass in malignant ventricular arrhythmia (MVA) after myocardial infarction.

Methods: Thirty myocardial infarction patients with complete electrophysiology and cardiac MRI data admitted from January 2012 to August 2017 were enrolled in the study. According to the results of intracavitary electrophysiological study, MVA developed in 16 patients (MVA group) and not developed in 14 patients (non-MVA group).
