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.

Atrial fibrillation symptoms

Atrial fibrillation is a common type of arrhythmia we encounter in our daily lives. So, what symptoms generally accompany atrial fibrillation? These symptoms are often characterized by sudden onset and cessation of palpitations, or chest tightness. During palpitations or chest tightness, dizziness often accompanies, and some patients may experience chest pain. If you exhibit these symptoms, don't panic. You can visit the cardiology outpatient department at a hospital. There, a doctor can perform an electrocardiogram or a Holter monitor test to see if you have atrial fibrillation. Blood tests can also be done to check if hyperthyroidism, a potential cause of atrial fibrillation, is present. Based on these examinations, follow the doctor's guidance and take medications as prescribed for treatment.

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 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 hormones be used for atrial fibrillation?

Patients with atrial fibrillation can use steroids, but in principle, it is best not to use them. This is because the use of steroids can cause excitement of the sympathetic nerves, leading to an increased heart rate, which in turn can trigger an episode of atrial fibrillation and cause uncomfortable heart symptoms, such as palpitations, chest tightness, shortness of breath, and difficulty breathing. Of course, atrial fibrillation is not a contraindication for the use of steroids. If the condition requires it, such as during an asthma attack or certain immunological diseases, steroids can be used. When using steroids, it is important to strengthen observation and inform the patient to seek timely medical attention at a hospital if symptoms of an atrial fibrillation episode, such as palpitations or chest tightness, occur.
