Atrial fibrillation (AF) is a supraventricular tachyarrhythmia that is strongly associated with cardiovascular (CV) disease and sedentary lifestyles. Despite the benefits of exercise on overall health, AF incidence in high‐level endurance athletes rivals that of CV disease patients, suggesting a J‐...

Atrial fibrillation, also called AF or AFib, is a quivery, fluttery heartbeat. You might also hear the doctor call it arrhythmia. It means your heart’s normal rhythm is out of whack. Because your blood isn't moving well, you're more likely to have heart failure. That's when your he...
Pulmonary vein isolation (PVI) using radiofrequency (RF) ablation is an established treatment for atrial fibrillation (AF). Although successful restoration of sinus rhythm after PVI is known to ultimately result in left atrial (LA) reverse remodeling, little is known about the impact of PVI on ...
An international consensus on nomenclature and classification of atrial fibrillation53proposed a subdivision of this arrhythmia into the following four categories: (1) initial (first-detected) event that may be symptomatic or asymptomatic and may or may not recur; (2) paroxysmal that terminates spontan...
What are the complications of atrial fibrillation? Heart failure: If the heart is unable to pump an adequate amount of blood to the body, as in some people with atrial fibrillation, the body begins to compensate by retaining fluid. This can lead to a condition called heart failure. Heart fa...
Last updated on May 4, 2025.Care notes Aftercare Ambulatory Discharge Inpatient Español Discharge Drugs Atrial fibrillation (A-fib) is an irregular heartbeat. It reduces your heart's ability to pump blood through your body. A-fib may come and go, or it may be a long-term condition. A...
Effects of BO on CaMKII signaling in atrium Chronic activation of calmodulin-dependent protein kinase II (CaMKII) signaling results in cellular remodeling and alterations in calcium (Ca2+) handling, ion channels, cell-to-cell coupling and metabolism leading to increased risk of atrial fibrillation37,...
Atrial fibrillation (AFib) is a problem with your heart's electrical activity. With AFib, your heart quivers, beats irregularly, or skips beats. It can't pump blood through its chambers and out to your body as well as it should. Sometimes, blood can pool in the heart and form clots, ...
and was found to increase cardiovascular death rates when given to patients with permanent AF in the Permanent Atrial Fibrillation Outcome Study Using Dronedarone on Top of Standard Therapy (PALLAS) study.47This drug also has gastrointestinal side effects that can be partially mitigated by taking the...
