Relationship between Ventricular Arrhythmia in the Acute Phase of Myocardial Infarction and Short- and Long-Term Prognosis.

130 patients with acute myocardial infarction (AMI). Group A (n=88) had Lown class ≤2 ventricular arrhythmia within 24 hours of onset (mean age 64.3, 69 male/19 female). Group B (n=42) had Lown class ≥3 ventricular arrhythmia within 24 hours of onset (mean age 66.7, 26 male/16 female).

Severe ventricular arrhythmia (Lown class ≥3) within 24 hours of AMI onset (Group B)

Mild or no ventricular arrhythmia (Lown class ≤2) within 24 hours of AMI onset (Group A)

Short-term (in-hospital) and long-term (up to 3 years) prognosis, including cardiac events and deathhard clinical
