SUMMARY

The arrhythmogenic potential of elevated serum free fatty acids (FFA) was investigated in closed-chest pigs following acute coronary artery occlusion. Animals both with and without ventricular irritability before the FFA rise were studied. No significant increase in PVC frequency occurred and only 1 out of 17 animals developed ventricular fibrillation in the 60min following acute FFA elevation. In this situation, FFA did not significantly influence the appearance of arrhythmias.
