What are the clinical associations of tachyarrhythmias in patients with acute myocardial infarction?
In acute myocardial infarction, serious ventricular arrhythmias are associated with higher mortality and left ventricular failure, while atrial fibrillation is linked to older age, left ventricular failure, and pericarditis.
Serious ventricular arrhythmias mark higher-risk AMI patients; hypothesis-generating for targeted interventions in prospective trials.
In 1505 patients with acute myocardial infarction (MI) serious ventricular arrhythmias were commoner in those with transmural ECG changes, and were associated with an increase in mortality and in the incidence of left ventricular failure (LVF) as well as higher peak serum lactic dehydrogenase (LDH) levels. Atrial fibrillation (AF) occurred more often in older patients and in those with LVF and clinical evidence of pericarditis.

McLean et al. (1975) conducted an observational in Acute myocardial infarction (n=1,505). Serious ventricular arrhythmias was evaluated on Mortality and incidence of left ventricular failure. In 1505 patients with acute myocardial infarction, serious ventricular arrhythmias were associated with an increase in mortality and left ventricular failure.
