Man sitting on a bench What Are the Symptoms Of AFib?

Some people feel them - others don't

You may or may not experience symptoms.

Some people show very clear atrial fibrillation (AFib) symptoms when they have an AFib episode. Others may go about their day without noticing any symptoms at all. The same person can sometimes feel that their heart is out of rhythm, and other times not feel it. Either way, AFib is a disease that needs to be taken seriously.

What can AFib feel like?

Symptoms can include anything from chest pains or a racing heartbeat, to feeling like your heart is jumping or "flip-flopping" in your chest. Play the Show Me More to learn what AFib symptoms can feel like through sight and sound. Make sure your sound is turned on.*

Here are a few other common AFib symptoms:

A fluttering feeling in the chest*
Chest pain or pressure*
Feeling out of breath*
Feeling weak or tired*
Dizziness and sweating*
Feeling faint or lightheaded*

   

AFib symptoms are serious. They are a sign that the heart isn’t working the way it should, and they can be so frightening that many people go to the hospital. Be sure to talk to your doctor about any symptoms you might have.
