Oily fish for arrhythmia?

A Harvard-based study suggests that eating oily fish high in omega-3 fatty acids may lower the risk of arrhythmia by improving the electrical signals that keep the heart beating regularly. The study also linked diets high in oily fish to lower resting heart rates, which are generally regarded as less of a risk than high resting heart rates, Food Production Daily reported. The study, published in the Journal of the American College of Cardiology, was based on dietary data collected from more than 5,000 people in the U.S. in 1989 and 1990. Researchers of course noted that further studies are needed to explore and confirm the results.
