The study authors noted that previous studies suggest that omega-3 fatty acids may accentuate vagal tone. Enhanced vagal tone has been shown to protect against ventricular fibrillation and sudden cardiac death, but may promote atrial fibrillation in select individuals. Dr. Aizer said the current study's findings may be influenced by the relatively young, healthy population of physicians where vagal tone may have a more significant impact.
"The message of this study is not to stop eating fish. AF is a complex condition that requires the interaction of a number of risk factors to develop. Fish may have different effects on different people. Lifestyle and dietary habits need to be tailored on an individual basis to promote overall health. Clearly, more investigation is needed to reach a more definitive answer about the multiple effects of omega-3 fatty acid on the heart's electrical function," Dr. Aizer concluded.
