The supplement fish oil has gained popularity since the 1970s. Fish oil is commonly derived from salmon, mackerel, tuna and mullet, and contains omega-3 essential fatty acids that may treat heart disease and cholesterol levels. Many patients with these conditions may also suffer from heart palpitations. Some evidence suggests fish oil may relieve heart palpitations, yet in some circumstances these patients should avoid the supplement altogether. Seek advice from your medical doctor before taking fish oil, especially if you suffer from heart palpitations.
Corelation
Heart palpitations are irregular heart beats. A common form of the condition is atrial fibrillation. Many patients with this condition may also have from other heart conditions and stroke, and take fish oil. The American Heart Association suggests taking 1 g of fish oil if you are diagnosed with coronary heart disease. A larger dose, between 2 and 3 g is suggested when attempting to lower high triglycerides. Considered a natural blood thinner, fish oil prevents blood clots from forming. During atrial fibrillation, the two upper chambers of the heart quiver instead of beating, causing blood to pool inside the heart's chambers. The result is the increased risk of blood clots forming that may lead to stroke.
Expert Opinion
Evidence is conflicting when determining if fish oil decreases irregular heart rhythms. More substantial scientific trials are needed to make a conclusive determination. According to Reuters.com, a 2010 study by Lankenau Institute for Medical Research, studied nearly 600 patients who received either fish oil or a placebo drug for six months. After an extended time, it was determined fish oil had no effect on the heart palpitations experienced by patients. Still, some patients will benefit from fish oil when taking the supplement for other cardiovascular benefits. Consult with your medical doctor if you are considering taking the supplement.
Defibrillators
Patients with extreme heart irregularities or who have implanted defibrillators are advised against taking fish oil supplements, states MedlinePlus. ScienceDaily.com reports a 2005 study by Portland Veterans Affairs Medical Center and Oregon Health & Science University showed an increase in irregular heart rhythms when patients with defibrillators consumed the supplement. The study concluded fish oil may actually be harmful and increase the risk of a heart attack in these patients.
Additional Fish Oil Safety
For many people, fish oil is a safe supplement to take. However, it is advised to not combine fish oil with prescription or over-the-counter medications that thin the blood. Fish oil decreases your blood's clotting time, and you are at risk of bleeding. If you take medications to reduce your blood pressure, be aware fish oil also slightly decreases blood pressure.
