The most common symptom of AFib is a rapid heartbeat or heart fluttering. Some people never know they have AFib because they never exhibit any symptoms, but other warning signs might include:
Fatigue or general lack of energy
Lightheadedness or dizziness
Chest pain or pressure
Shortness of breath
Fainting
It’s important to speak to your physician if you have any concerns about AFib symptoms or suspect you could have the condition.
