Atrial fibrillation is the most common clinical arrhythmia. An electrocardiogram reveals abnormal fluctuations in the atria, which are fast and disordered with some fibrillating waves, known as atrial fibrillation. Diseases causing atrial fibrillation are often associated with structural heart disease. Common conditions include rheumatic heart disease, heart failure, pulmonary heart disease, viral myocarditis, coronary artery disease, and congenital heart disease. Atrial fibrillation can also occur in conditions that cause sympathetic or parasympathetic nerve activity changes, with hyperthyroidism being a common related disease.

Is atrial fibrillation the same as atrial flutter?

Atrial fibrillation, also known simply as AFib, is the same disease just referred to by different names. Atrial fibrillation is caused by various reasons leading to pathological changes in cardiac contractility and conductivity. By using a stethoscope, a doctor can detect irregularities in heart rate and varying intensities of heart sounds. Electrocardiogram (ECG) tests can record the distinctive waveforms of atrial fibrillation. Rapid atrial fibrillation requires medication for treatment. If not effectively treated, long-term atrial fibrillation can lead to heart failure, resulting in insufficient blood supply to the body and causing significant harm.

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.

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 atrial fibrillation be completely cured?

Regarding whether atrial fibrillation can be completely cured, it essentially depends on the definition of being completely cured. If the criterion is complete cessation of medication, then many patients cannot achieve this. However, if the standard is conversion of atrial fibrillation back to normal sinus rhythm, then it is achievable for many patients, such as those with paroxysmal atrial fibrillation, who suffer from recurrent episodes and do not respond well to medication. In such cases, radiofrequency ablation might be attempted, and there is a high likelihood that after the treatment, the rhythm will convert to sinus rhythm. In this sense, some people can be considered cured. However, whether anticoagulation therapy can be discontinued depends on their thromboembolic risk score. This means that even if atrial fibrillation converts to sinus rhythm after radiofrequency ablation, some patients still need long-term anticoagulant medication. Therefore, from the perspective of discontinuing medication, such patients with atrial fibrillation are not considered cured.

Can atrial fibrillation be cured?

Atrial fibrillation is a common arrhythmia in daily life. Many patients often ask their doctors after being diagnosed with atrial fibrillation, "Can my atrial fibrillation be cured?" The answer is affirmative. With the advancement of medical technology, some patients can be completely cured of atrial fibrillation, which needs to be analyzed and judged based on the treatment methods for atrial fibrillation. First, medication treatment, which is currently the mainstream method for treating atrial fibrillation. Most patients use medication treatment, but it cannot effectively cure atrial fibrillation. Second, radiofrequency ablation treatment, which is a minimally invasive means of treating atrial fibrillation. This technology has become very mature, and many patients have achieved complete cure of atrial fibrillation through radiofrequency ablation treatment. Third, surgical treatment, where a portion of the patients undergo a Maze procedure during surgery, which can also achieve the purpose of curing atrial fibrillation.
