Is it normal for my heart to do this?

My heart has been acting weird lately.
Each day, out of nowhere, my heartbeat will randomly and dramatically slow down for few seconds until returning to normal. It repeats itself 2-3 times a day and I feel funny when it happens.
Anyway, Is this a...

normal thing or???

Go to a doctor SOON.
You're pretty young, so heart desease is out of the question.

If you feel strange when it happens, it's probably because your blood pressure dropped. I suggest you go to the doctor and check that out, because it's not normal.

I get that too... :/
