Cardiac or heart arrhythmia, also known as cardiac dysrhythmia, is nothing but a disturbance or fluctuation in the regular rhythm of the heartbeat. It can occur due to irregular electrical activity of the heart, and some forms are commonly referred to as heart palpitations.
Although most heart arrhythmias are not life-threatening, some can be indicative of a cardiac arrest which, if not attended in time, can even lead to death. There are various conventional medicines which help with the pounding or fluttering sensations; however certain dietary measures can help control an irregular heartbeat.
There is growing evidence that increasing the intake of omega-3 fatty acids can help prevent as well as control heart arrhythmia. [1,2,3] Alpha-linolenic acid (ALA) is the parent fatty acid of the omega-3 family, with two other major long chain derivatives—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
One of the richest sources of ALA in the North American diet are flaxseeds. A 2004 study carried out by Canadian scientists was able to highlight the anti-arrhythmic properties of these tiny seeds. The study, which was carried out in rabbits, was able to demonstrate that dietary flaxseed exerts antiarrhythmic effects, possibly through shortening of the action potential. 
Other rich sources of omega-3 fatty acids are walnuts and fatty fish such as salmon, cod, tuna and halibut.
How To Take Them
- There are several ways to incorporate flaxseeds in your daily diet. The easiest one is to sprinkle one tablespoon on your breakfast cereal.
- Grind some flaxseeds and add the powder to your sandwich mustard or mayonnaise.
- Add a handful to your fresh juice or smoothie. Here’s how you can make a delicious smoothie with leafy greens & flaxseeds.
- Their nutty taste can also enhance the flavor of your baked goods.
