There is no special diet for patients with arrhythmias. Arrhythmias often occur on top of organic heart disease, so a low salt and low fat diet is recommended. A plant-based diet is recommended, such as a Mediterranean diet with more fruits, vegetables, whole grains, legumes and nuts, and less saturated fatty acids, cholesterol and sodium. For meat, it is recommended to focus on lean and white meat. White meat mainly refers to skinless poultry and fish, and poultry refers to chicken, duck and goose. Be careful to maintain a healthy weight and reduce stress as much as possible. Cardiac arrhythmias can also occur in endocrine diseases, such as hyperthyroidism and other diseases, which require attention to the intake of foods with low iodine content and dynamic monitoring of thyroid function to adjust the relevant treatment in a timely manner.
