Atrial fibrillation can occur in healthy individuals, sometimes triggered by emotional excitement, surgery, exercise, or excessive drinking. It often occurs in patients with existing cardiovascular diseases, such as rheumatic heart disease, coronary artery disease, hypertensive heart disease, hyperthyroidism, constrictive pericarditis, myocarditis, infective endocarditis, and chronic pulmonary heart disease. Atrial fibrillation can also occur in middle-aged and young adults without cardiac diseases, known as lone atrial fibrillation.

Can atrial fibrillation be cured?

Can atrial fibrillation be cured? Many patients often ask doctors this question, and the answer is affirmative. With the development of minimally invasive interventional treatment techniques, some patients with atrial fibrillation have been cured after radiofrequency ablation treatment and have not experienced any recurrence. As for which atrial fibrillation cases are suitable for radiofrequency ablation treatment, I suggest that if the atrial fibrillation recurs repeatedly and the symptoms are quite apparent, and the effect of medication is not ideal, one should consult a specialist cardiologist to see if radiofrequency ablation treatment is appropriate.

Nursing Care for Patients with Atrial Fibrillation

Atrial fibrillation (AF) refers to atrial fibrillation, caused primarily by organic heart diseases, commonly seen in coronary heart disease, rheumatic heart disease, cardiomyopathy, and pulmonary heart disease, as well as certain metabolic disorders such as hyperthyroidism. Patients with AF can experience impacts on cardiac function, and in severe cases, may develop heart failure. Nursing care primarily involves ensuring the patient rests and avoids excessive fatigue. Mild physical activities can be performed, and it is advisable to eat easily digestible foods and avoid spicy foods to reduce gastrointestinal irritation and lessen the burden on cardiac function. Attention should be paid to sleep, avoiding smoking and alcohol, routinely checking the electrocardiogram (ECG), and seeking timely medical treatment at a hospital if special conditions arise.

What medicine is used for atrial fibrillation?

The current medications for atrial fibrillation mainly include three types: the first type controls the ventricular rate, which ensures the basic function of the patient's heart and minimizes the cardiac dysfunction caused by atrial fibrillation. This includes drugs such as receptor blockers and calcium channel antagonists, digoxin, amiodarone, and others. The second type of drugs are those used for cardioversion. The third type of drugs are those used to prevent embolism, which are anticoagulants. Currently, the main drugs include warfarin, new anticoagulants such as dabigatran and rivaroxaban, and intravenous medications like low molecular weight heparin calcium and nadroparin.

Can elderly people with atrial fibrillation take calcium tablets?

Elderly patients with atrial fibrillation can take calcium supplements if their condition requires it, such as those with osteoporosis. Generally, taking calcium supplements does not affect atrial fibrillation nor does it impact the effectiveness of the medications treating atrial fibrillation. However, calcium supplements themselves do not have an effect on atrial fibrillation and cannot reduce the occurrences of atrial fibrillation episodes. When atrial fibrillation occurs repeatedly, it is necessary to take anticoagulant medications under the guidance of a doctor, such as warfarin or the newer oral anticoagulant medication rivaroxaban, to prevent the formation of blood clots and avoid complications caused by clots from atrial fibrillation. Additionally, if the heart rate is fast, it is appropriate to take medications that control heart rate to improve symptoms.

What is good to eat for atrial fibrillation?

Atrial fibrillation is a common type of arrhythmia in the elderly. After being diagnosed with atrial fibrillation, there are indeed some dietary considerations to be aware of. Here are a few aspects to pay attention to: First, eat less spicy and greasy food. Spicy and greasy foods can often irritate our stomach, leading to discomfort and potentially triggering an episode of atrial fibrillation. Second, eat more vegetables and fruits. Vegetables and fruits are often rich in dietary fiber and vitamin C, which are beneficial to our health. Third, balance meat and vegetable intake and ensure nutritional balance. Foods such as pork, fish, and lean meats are rich in high-quality protein, which is beneficial for our health.
