Atrial fibrillation
What does atrial fibrillation mean?
Atrial fibrillation, often abbreviated as AF, is a common type of cardiac arrhythmia in the elderly. Medically, it is described as a disorderly and irregular heart rhythm without a rhythm in the atria. In layman's terms, for example, if our heartbeat is like people queuing up to buy tickets, normally everyone comes one by one in an orderly manner. Atrial fibrillation, however, is like everyone rushing to the ticketing area at once. Consequently, some people might run fast, others slow, some take up more space because they are heavier, and others less because they are thinner. Atrial fibrillation is similar to this scenario.
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 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.
Atrial fibrillation is caused by what?
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.
How is atrial fibrillation surgery performed?
Frequent atrial fibrillation attacks with a rapid ventricular rate, in cases unresponsive to drug treatment, can be managed by atrioventricular node ablation followed by the placement of a ventricular demand or dual-chamber pacemaker. Other treatment methods include radiofrequency ablation, surgical operations, and implantation of atrial defibrillators. In recent years, there have been significant advances in the methods for atrial fibrillation ablation, and the indications for atrial fibrillation ablation have been expanded. However, the success rate remains suboptimal and the recurrence rate is relatively high. Currently, international guidelines still categorize radiofrequency ablation as a second-line treatment for atrial fibrillation, not as the first choice treatment.
