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.

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.

Can atrial fibrillation cause cerebral infarction?

Patients with chronic atrial fibrillation have a relatively high incidence rate of embolism. For instance, those with a history of embolism, valvular disease, hypertension, diabetes, elderly patients, left atrial enlargement, and coronary artery disease are at increased risk of embolism. Atrial fibrillation is an independent risk factor for stroke. As age increases, the incidence of stroke in patients with atrial fibrillation also increases annually; atrial fibrillation doubles the mortality rate of stroke and significantly increases the disability rate. At the same time, atrial fibrillation also significantly increases the risk of recurrent stroke. Studies show that the incidence of stroke within the first year after a stroke is 6.92% in patients with atrial fibrillation, compared to 4.7% in those without atrial fibrillation. Therefore, anticoagulation therapy is the primary strategy for managing atrial fibrillation.

Can atrial fibrillation be cured?

The treatment of atrial fibrillation, first and foremost, should actively seek the primary disease and inducing factors of atrial fibrillation, and make corresponding treatments. Currently, the treatment of atrial fibrillation mainly includes two types: one is drug treatment. Since patients with atrial fibrillation have a higher incidence of embolism and may have a history of embolism, valve disease, hypertension, diabetes, older patients, left atrial enlargement, and coronary heart disease, which can increase the risk of embolism, therefore, such patients should be advised to undergo long-term anticoagulation treatment. Another type of drug treatment is to control the ventricular rate. When drug treatment is ineffective, surgical treatment can be chosen, and the main surgical treatment currently is radiofrequency ablation.

Is heart palpitation the same as atrial fibrillation?

Palpitations are considered a disease term in Chinese medicine, while atrial fibrillation is a medical term in Western medicine. Generally, if there is a correlation between Chinese and Western medical terminology, palpitations can correspond to atrial fibrillation, but not all cases of palpitations are atrial fibrillation. In Chinese medicine, palpitations refer to a subjective feeling of unease or discomfort in the chest, and a feeling of irregular heartbeats. For example, some people may feel their heartbeat distinctly even when their heart rate is not fast, especially when their blood pressure is high; this is also considered palpitations. Additionally, some people may experience a rapid "thumping" heart rate after physical exertion or when they have a fever, which is also a manifestation of palpitations. There are also healthy, sensitive young individuals who can feel their heartbeat while lying down quietly or during sleep, which is also classified as palpitations. However, palpitations that are caused by heart arrhythmias, like atrial fibrillation, where individuals can feel their heart beating rapidly and experience anxiety, are specifically indicative of atrial fibrillation; other types are not considered the same.

Can atrial fibrillation heal itself?

No. Atrial fibrillation, often abbreviated as AFib, is becoming more common as society ages. Many patients ask their doctors if AFib will go away on its own. The answer is no, AFib will not resolve itself. Therefore, once diagnosed with AFib, it is essential to visit a hospital and follow the guidance of a doctor. Proper medication under medical supervision can control symptoms, prevent complications, ensure a good quality of life, improve long-term outcomes, and extend life expectancy.
