Your heart works quietly in the background every day — but when its rhythm becomes irregular, it may be a sign of atrial fibrillation (AFib), the most common type of irregular heartbeat.
In AFib, the heart’s upper chambers beat in a fast and chaotic way instead of a steady rhythm. This can affect how efficiently blood flows through the heart. When blood doesn’t move properly, it may form clots — increasing the risk of stroke by up to five times.
AFib doesn’t always cause obvious symptoms. Some people may notice:
But many experience no symptoms at all — often discovering it only during routine healthchecks.
Risk increases with age, especially after 60. High blood pressure, heart disease, diabetes, obesity, smoking, alcohol use, sleep apnea, and thyroid conditions can also raise the likelihood of AFib.
When detected early, AFib can be managed. Treatment helps control heart rhythm and reduces stroke risk.
Today, some blood pressure monitors and wearable devices can help detect irregular heart rhythms, encouraging earlier medical evaluation.
Simple lifestyle habits can support heart health:
Listening to your heart — and acting early — can make a meaningful difference in your long-term health.
