Nutrition and metabolism

Purpose of review There is now a considerable factual basis from laboratory and clinical trials that omega-3 fatty acids of fish oil will prevent fatal arrhythmias in animals and humans and this is the focus of the review.

Recent findings Several recent trials in humans have strengthened the evidence that omega-3 fatty acids may prevent arrhythmias although this has not been a uniform finding.

Summary Since there are at present some 400 000 deaths annually in the US alone and millions more worldwide, what has been learned about the antiarrhythmic actions of omega-3 fatty acids has considerable potential public-health benefit.
