2024年3月8日 · Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm. An irregular heart rhythm is called an arrhythmia. AFib can lead to blood clots in the heart. The condition also increases the risk of stroke, heart failure and other heart-related complications.

2024年10月8日 · Atrial fibrillation (AF) is the most common sustained arrhythmia. It is characterised by disorganised atrial electrical activity and contraction. The incidence and prevalence of AF is increasing. Lifetime risk over the age of 40 years is ~25%.

2023年8月2日 · A doctor can identify some types of atrial fibrillation by looking at an electrocardiogram, or EKG. Learn about their characteristics and how they are identified in this MNT Knowledge Center...

Atrial fibrillation is a rapid, irregularly irregular atrial rhythm. Symptoms include palpitations and sometimes weakness, effort intolerance, dyspnea, and presyncope. Atrial thrombi may form, causing a significant risk of embolic stroke. Diagnosis is by electrocardiography.

2024年7月25日 · Atrial fibrillation (Afib) is an irregular heart rhythm that begins in your heart’s upper chambers (atria). Symptoms include fatigue, heart palpitations, trouble breathing and dizziness. Afib is one of the most common arrhythmias. Risk factors include high blood pressure, coronary artery disease and having obesity.

2024年5月15日 · Atrial fibrillation, often called AFib or AF, is the most common type of treated heart arrhythmia. An arrhythmia is when the heart beats too slowly, too fast, or in an irregular way.

This chapter discusses the classification, causes (electrophysiology), ECG /EKG diagnosis, risk factors and management (treatment) of atrial fibrillation. Includes a complete e-book, video lectures, clinical management, guidelines and more.

Afib is caused by extremely fast and irregular beats from the upper chambers of the heart (usually more than 400 beats per minute). A normal, healthy heartbeat involves a regular contraction of the heart muscle. A contraction happens about once per second at rest and increases with exercise.

Atrial fibrillation is generally considered a tachyarrhythmia, (an arrhythmia with a heart rate of more than 100 beats per minute). Patients experiencing atrial fibrillation generally have the following characteristics: What Are Signs or Symptoms of Atrial Fibrillation? Some patients are asymptomatic and may not know they have atrial fibrillation.

Atrial fibrillation, also known as AFib or AF, can lead to blood clots, stroke, heart failure and other heart-related complications. What are the Symptoms of Atrial Fibrillation? People with AFib are more likely to have a stroke. Our guide can help you learn more about AFib, ways to manage it and how to reduce your risk for stroke.
