Atrial fibrillation Archive

Symptoms of atrial fibrillation include a fluttering, pounding sensation in the chest and a lightheaded, dizzy, or breathless feeling. But about a quarter of people with this disorder don’t notice any symptoms.

Insomnia is linked to an increased risk of atrial fibrillation (afib), a heart rhythm disorder, according to a 2026 study. Insufficient sleep may trigger physiological and hormonal changes that may leave people more susceptible to afib.

Recent advances in caring for people with strokes include expanded access to medications and clot removal procedures. In certain cases, these therapies may be done up to 24 hours after stroke symptoms first appear.

Wearing an Apple Watch capable of recording an electrocardiogram may increase the detection of atrial fibrillation in older adults at increased risk for stroke, according to a 2026 study.

After a successful catheter ablation to treat atrial fibrillation, some people may safely stop taking anti-clotting medications. But the decision to discontinue those drugs depends on a person's underlying risk of stroke rather than the success of the procedure.

People with atrial fibrillation (afib) who drank an average of one cup of caffeinated coffee daily had a lower risk of recurrent afib compared to those who avoided caffeine, according to a 2025 study.

Many people with atrial fibrillation (afib) - a rapid, irregular heart rhythm - need to control symptoms, such as the feeling that the heart is racing or fluttering. Medication options include drugs that slow down the heart or help restore its rhythm. Because afib can also increase the risk of blood clots that can lead to a stroke, many of these people also need to take clot-preventing medications.
