Can you have atrial fibrillation and not know it?

Hello, I'm a healthcare professional with a background in cardiology. I can provide you with information regarding atrial fibrillation and its symptoms. Yes, it is possible to have atrial fibrillation (AFib) and not be aware of it. Atrial fibrillation is the most common type of arrhythmia, which is an irregular heartbeat. Some people with AFib may experience symptoms such as palpitations, shortness of breath, fatigue, or chest pain. However, others may not have any noticeable symptoms at all, especially if the heart's pumping action remains relatively efficient. Without noticeable symptoms, it can be challenging to self-diagnose AFib. It's often detected during a routine physical examination when a doctor listens to the heart or during a medical evaluation for another condition. In some cases, AFib is discovered incidentally when an electrocardiogram (ECG) is performed for unrelated reasons. It's important to note that asymptomatic AFib can still pose risks. Even without symptoms, it increases the risk of stroke and other complications. Therefore, regular check-ups and being attentive to any changes in your health can be crucial for early detection.

Can You Have AFib and Not Know It? ... Nearly a quarter of the estimated 2.7 million people who have AFib have no symptoms at all. The problem is called silent AFib. With this condition, the chambers on the top of your heart, called the atria, flutter instead of beating normally, which can put stress on the heart muscle.
