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.

Can a normal heart rate have atrial fibrillation?

Atrial fibrillation includes paroxysmal atrial fibrillation and persistent atrial fibrillation. Patients with paroxysmal atrial fibrillation may have a normal heart rate during non-attack periods. In contrast, those with persistent atrial fibrillation continuously experience atrial fibrillation rates, presenting with irregular heart sounds of varying intensity. A normal electrocardiogram displays P waves, QRS complexes, and T waves. However, patients with atrial fibrillation either do not exhibit P waves or show irregularly sized, serrated P waves resembling dog teeth, suggesting atrial fibrillation. Therefore, although atrial fibrillation is associated with arrhythmias, individuals with paroxysmal atrial fibrillation may have a normal heart rate but experience repeated palpitations, chest tightness, discomfort in the precordial region, and fatigue. Therefore, patients who frequently experience palpitations should undergo a 24-hour Holter monitor test or consider esophageal electrophysiological examinations to rule out arrhythmic disorders, such as atrial fibrillation and supraventricular tachycardia. Hence, a normal heart rate does not exclude the presence of atrial fibrillation in individuals with corresponding symptoms.

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.

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 people with atrial fibrillation drink alcohol?

Atrial fibrillation is a common arrhythmia among many middle-aged and elderly people, and in our country, which has a strong culture of alcohol consumption, many people enjoy drinking. So, can you drink alcohol if you have atrial fibrillation? My advice is that it's best not to drink. Modern medical research has shown that alcohol can potentially trigger attacks of atrial fibrillation, and in our clinical practice, we often find that many patients experience an onset of atrial fibrillation by drinking alcohol, sometimes even necessitating hospital treatment due to the episodes. Therefore, it is recommended that patients with atrial fibrillation avoid or minimize alcohol consumption.

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.
