Causes of Atrial Fibrillation The most common cause of AFib is a problem with your heart's structure. It can happen as a result of: Previous heart surgery Heart attack A problem with your heart's natural pacemaker An issue you were born with (congenital heart defect) Hear...
heart failureAtrial fibrillation (AF) and chronic heart failure (HF) are two common cardiac diseases, affecting 1–2% of the population [1–3] with a prevalence that rises steeply with age. AF and HF are conditioned by common risk factors and frequently coexist [3]. AF is the most common...
As with atrial fibrillation, atrial flutter is usually not life-threatening when it's properly treated. Risk factors Certain factors may increase your risk of developing atrial fibrillation. These include: Age.The older you are, the greater your risk of developing atrial fibrillation. Heart disease...
CONCLUSION: In patients with HF, AF is associated with an increased risk of death only in patients with underlying IHD. 展开 关键词: Heart failure Atrial fibrillation Ischaemic heart disease Prognosis DOI: 10.1016/S0735-1097(10)60270-7 被引量: 45 ...
Atrial fibrillation, also called A-fib, is the most common type of heart arrhythmia. In fact, A-fib affects an estimated 3-6 million people in the United States alone.1With A-fib, the upper heart chambers (the atria) beat irregularly. As a result, blood doesn’t move well into the ...
心房纤维颤动(Atrial fibrillation),英文亦简 称A-fib或atrial fib。心房纤维颤动是心律失常的表现。 The heart’s rhythm is controlled by electricalsignals in the heart. The sinus node sendselectrical signals to the rest of the heart.These signals cause the heart to contractand pump blood. Normally,...
Atrial fibrillation (AF) is the most common sustained arrhythmia worldwide and has a strong association with heart failure (HF). It often remains unclear if HF is the cause or consequence of AF due to the complexity of the processes that are involved in both the perpetuation of AF and the...
Atrial fibrillation (Afib) is an abnormal heart rhythm caused by erratic electrical signals in the heart. Atrial fibrillation is a progressive disease that worsens.
Valvular atrial fibrillation This type affects people who have an artificial heart valve or valve disease such as valvular stenosis (when one of your heart valves stiffens) or regurgitation (when a valve isn’t closing properly, which lets some blood flow the wrong way). Your chance of getting...
Atrial fibrillation ( AF or Afib ) is a supraventricular tachyarrhythmia and the most common kind of arrhythmia. It is caused by rapid, uncontrolled atrial contractions and uncoordinated ventricular responses. There are many conditions that can cause AF , usually damage to the heart (e.g., ...
