Atrial fibrillation
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.
The difference between premature beats and atrial fibrillation
Premature beats refer to the early discharge of the heart's impulses. Premature beats can be divided into atrial premature beats, ventricular premature beats, and junctional premature beats. Atrial premature beats occur when the impulse is prematurely emitted from the atrium; ventricular premature beats occur when the impulse is prematurely emitted from the ventricles; junctional premature beats occur when the impulse is prematurely emitted from the atrioventricular junction. Atrial fibrillation is characterized by the atria losing their normal pattern of contraction and relaxation, replaced by irregular quivering. Both premature beats and atrial fibrillation are common arrhythmias that can be identified on an electrocardiogram.
What are the symptoms of atrial fibrillation?
The most common symptoms of atrial fibrillation episodes are chest tightness, palpitations, shortness of breath, and fatigue. When atrial fibrillation causes a significant decrease in cardiac output, it can also lead to insufficient cerebral blood supply, causing symptoms such as dizziness and blackouts. Occasionally, it may also cause fainting in patients. When coronary artery blood supply is insufficient, it can also trigger angina attacks. Moreover, if atrial fibrillation leads to heart failure, it can cause significant respiratory difficulty. Atrial fibrillation is a common arrhythmia clinically. The treatment of atrial fibrillation should be based on the specific situation, choosing either cardioversion or controlling the ventricular rate. Cardioversion can be achieved through medication or radiofrequency ablation surgery, while controlling the ventricular rate can be managed with β-blockers, amiodarone, digoxin, and other drugs. In treating atrial fibrillation with ventricular rate control, patients need to take anticoagulants long-term to prevent the occurrence of peripheral arterial embolism. (Please follow medical advice regarding medications.)
How to diagnose atrial fibrillation?
Atrial fibrillation, abbreviated as AF, refers to rapid and irregular beating of the atrial chambers of the heart. How should one be examined after being diagnosed with atrial fibrillation? Generally, the examination for atrial fibrillation involves the following aspects: First, blood tests, such as thyroid function tests, to see if there is hyperthyroidism causing the atrial fibrillation. Second, echocardiography. This test can reveal whether there are any heart valve diseases or myocardial diseases that might lead to atrial fibrillation. Third, electrocardiogram (ECG) and Holter monitor. Both ECG and Holter monitoring are effective and non-invasive tests that confirm the diagnosis of atrial fibrillation.
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.
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 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.
Nursing Care for Patients with Atrial Fibrillation
Atrial fibrillation (AF) refers to atrial fibrillation, caused primarily by organic heart diseases, commonly seen in coronary heart disease, rheumatic heart disease, cardiomyopathy, and pulmonary heart disease, as well as certain metabolic disorders such as hyperthyroidism. Patients with AF can experience impacts on cardiac function, and in severe cases, may develop heart failure. Nursing care primarily involves ensuring the patient rests and avoids excessive fatigue. Mild physical activities can be performed, and it is advisable to eat easily digestible foods and avoid spicy foods to reduce gastrointestinal irritation and lessen the burden on cardiac function. Attention should be paid to sleep, avoiding smoking and alcohol, routinely checking the electrocardiogram (ECG), and seeking timely medical treatment at a hospital if special conditions arise.
"Heart atrial fibrillation" refers to what?
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.
How is atrial fibrillation treated?
Atrial fibrillation is a common type of arrhythmia in our daily lives, and it has many dangers. First, it produces symptoms; when atrial fibrillation occurs, patients often experience palpitations and chest discomfort. Second, it can induce heart failure. Third, it can cause complications such as cerebral infarction. Therefore, the treatment of atrial fibrillation is usually divided into the following types: first, pharmacological treatment, such as using amiodarone to maintain sinus rhythm and taking warfarin to prevent thrombosis. Second, surgical treatment, such as radiofrequency ablation therapy, which is a minimally invasive method and is hoped to prevent further episodes of atrial fibrillation.
