Certain types of foods tend to aggravate certain arrhythmias.
Your doctor might recommend that you avoid specific foods that can trigger your arrhythmia. To keep your heart as healthy as possible, try to eat heart-healthy foods.
Eating certain foods and drinking certain beverages may provoke your arrhythmia. Be aware of which substances have an effect on your arrhythmia and how to avoid them. In general, small amounts of any food will not trigger an arrhythmia. But in larger quantities, some foods can aggravate your heart and cause your arrhythmia to occur or get worse. Be aware of the foods listed below, as they may trigger your arrhythmia. It is a good idea to talk with your doctor about your diet. You may want to specifically talk about the items in the table below.
How it aggravates your arrhythmia
||Alcohol can trigger arrhythmias in some people.|
||Caffeine is a stimulant, which speeds up your heart rate. Caffeine can trigger arrhythmias in some people.|
Alcohol can cause arrhythmias in people with normal hearts and can cause heart conditions that result in arrhythmias. People who drink heavily can develop a weak heart (alcoholic cardiomyopathy). When this occurs, they can have various arrhythmias including atrial fibrillation, atrial flutter, and ventricular tachycardia. The heart may return to normal if the person stops drinking, and the risk of recurrent arrhythmias will decrease. Alcohol can directly injure heart cells and cause extra heartbeats and supraventricular tachycardias. Atrial fibrillation may occur after a drinking binge.
The most common example of a food that triggers arrhythmias is caffeine. Caffeine is present in coffee, tea, colas, various other soft drinks, and chocolate. People with almost any kind of rapid arrhythmia and palpitations from any cause tend to have more frequent arrhythmias and palpitations after ingesting caffeine. So people who have fast arrhythmias should avoid caffeine-containing foods. Caffeine can make symptoms such as palpitations stronger and more noticeable. Since caffeine is a stimulant, it speeds up your heart rate, making your heart beat even faster and making symptoms like chest pain or lightheadedness worse. In some cases, large amounts of caffeine can even trigger a new episode of an arrhythmia by irritating your heart's conduction system.
Many weight-loss diets can be harmful to your heart if you have an arrhythmia. Fad diets such as liquid-based programs or high-protein regimens can affect the concentrations of electrolytes in your bloodstream. This can, in turn, cause problems with your heart's electrical system, which relies on electrolytes to function properly. If you have experienced an arrhythmia in the past, you should be cautious of fad diets. In order to avoid recurrences of your arrhythmia, always check with your doctor before making drastic changes to your eating habits.
When taken at higher levels, ephedra—an herb used by some people for cold and allergy symptoms and to improve sports performance—can cause drastic increases in blood pressure as well as cardiac arrhythmias. Ephedra, also called ma huang, has been linked to heart attacks, strokes, and some deaths.
