Effects of arachidonic, linoleic, linolenic and oleic acid on experimental arrhythmias in cats, rabbits and guinea-pigs

Prostaglandins

Abstract

Antiarrhythmic effects of the Prostaglandin (PG) precursors arachidonic and Linoleic acid were demonstrated on three models of experimental arrhythmias, whereas the fatty acids linolenic and oleic acid proved to be ineffective in these models. In ouabain-induced arrhythmias infusions of arachidonic acid (1, 0 mg/kg/min) caused a strong antiarrhythmic effect in 80 percent of the animals. On the same model linoleic acid showed a maximum effct in 40 percent of the animals. BaCl2-induced arrhythmias were abolished by arachidonic and linoleic acid in 60 percent and 66 percent of the rabbits, respectively. Pretreatment by indomethacin reduced the antiarrhythmic effects of linoleic acid from 40 percent to 9 percent on ouabain-induced arrhythmias in cats. The results suggest a participation of PG synthesis in the antiarrhythmic effect of PG precursors.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.
