AF is when your heart beats in an irregular way. Sometimes it will beat very fast and not in a steady pattern.
This can lead to problems because your heart might not pump blood very well, and there is a risk of blood clots forming inside of your heart.
What you may feel with AF (symptoms):
- A feeling of fluttering in your chest (palpitations)
- Chest tightness
- Chest heaviness ‘like an elephant is sitting on my chest’
- Shortness of breath
- Dizziness
- Lack of energy.
