It is common for your heart (if it has been beating fast) to skip beats.
Your heart knows what it's doing. If it has been beating fast for a period of time. It isn't uncommon for it to skip a few beats here and there to give itself a bit of rest.
Most people can feel them and it can cause some anxiety
in some people when it happens.
It is normal.
If it should become a problem to the point where you have symptoms other than what you described?
Have it checked out. AN EKG will reveal anything abnormal.
