You should take ECG if and when you feel heart palpitations. Also take cholesterol profile. Eat a low-cholesterol, low-fat diet, which includes cottage cheese, fat-free milk, fish, vegetables, poultry, and egg whites. Use monounsaturated oils such as olive, peanut, and canola oils or polyunsaturated oils such as corn, safflower, soy, sunflower, cottonseed, and soybean oils. Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, olives, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods.
