A

rather than contracting properly, the chambers at the top of your heart quiver (demonstrate with hands)

blood not being pumped as effectively - explains palpitations / dizzy sensation

Sometimes it’s not triggered by anything in particular but there are risk factors for it - high blood pressure can increase your risk (causes structural change to heart over many years)
