Your heart feels like it’s racing or skipping beats. There are many reasons that this can happen. You may have just gotten some good news and you’re excited. It could be that you’re about to start a new job and you’re nervous. Or maybe you drank too much coffee this morning and now you have caffeine jitters.

An irregular heartbeat may also be something more serious: a condition called atrial fibrillation, or AFib. AFib is a heart rhythm disorder, or arrhythmia, in which electrical signals in your heart don't travel the right way. It’s like a miscommunication that causes your heart’s two upper chambers (atria) to beat too fast.

AFib symptoms include:

➡️A skipped heartbeat followed by a thump

Heart palpitations or a fluttering sensation.

➡️Sweating.

➡️Chest pain.

➡️Dizziness.

➡️Fatigue and weakness.
