atrial fibrillation is characterized by a rapid pulse and irregular heart rhythm. It is a more common cardiac arrhythmia. AF may lack symptoms, although fatigue and impaired exercise ability are common symptoms. This column will discuss exercise testing and training recommendations as well as special...
Atrial fibrillation (AF) is an abnormality of the heart's rhythm that is characterized by rapid and irregular activation of the atria. AF was first described in humans in 19061 and is now recognized to be the most common sustained cardiac arrh...
Atrial fibrillation is a condition characterized by chaotic electrical activity in the atria, resulting in an irregular heartbeat and pulse. It is a common cardiac arrhythmia that affects approximately 1% of the population, with higher prevalence in older individuals. Atrial fibrillation can be classifi...
While electrical, structural, and contractile remodeling are well-known contributors to AF incidence and progression [9], the role of cardiac metabolic remodeling in AF remains largely unexplored. Atrial fibrillation is characterized by irregular high-frequency excitation and contraction, which disrupts the...
Atrial fibrillation is characterized by a rapid and irregular heartbeat, leading to symptoms such as palpitations, fatigue, dizziness, and more. If AF resolves spontaneously within 7 days, it is classified as paroxysmal atrial fibrillation; if it persists beyond 7 days, it is classified as persist...
Atrial fibrillation (AF) has strong associations with other cardiovascular diseases, such as heart failure, coronary artery disease (CAD), valvular heart disease, and hypertension. It is characterized by an irregularly irregular and often rapid heart rate. The exact mechanisms by which cardiovascular ...
Atrial fibrillation is characterized by a rapid and irregular heartbeat caused when the top chambers of the heart quiver erratically, sometimes faster than 200 times per minute. The condition can have a significant negative impact on an individual's quality of life, causing heart palpitations, chron...
Atrial fibrillation (AF) is characterized by a progression from paroxysmal to persistent or permanent AF. Recent studies have shown that AF progression is related to a worse morbidity and mortality, and poorer outcomes of radiofrequency catheter ablation (RFCA). We previously showed that left ventric...
Atrial fibrillation is a commonly encountered rhythm disturbance characterized by an irregular and often rapid pulse rate. Mechanically, the rapid and irregular depolarization of the atria causes an alteration in the length of individual cardiac cycles resulting in irregular filling of the left ventricle...
