I'm a 19 year old female, 5"9 and a healthy weight
Last night my heart suddenly started beating really really fast. It felt as if there was a big weight resting on mychest..but it wasn't difficult to breathe. Everytime I would try to time the beats per minute I could only reach 20 beats in 5 seconds before I kept panicking thinking I was having a heart attack. I tried lying down and taking deep breaths to calm myself down. My arms felt very weak, especially my left and there was pressure along the left side of my jaw. I never experienced any pain just a lot of pressure, racing heart and weak arms,etc. My heart beat slowed down after about 45 minutes but continued to beat fairly fast for the next 2 hours

I had taken a few hits of mairjuana in the previous hour before this happened but didn't have enough to be anywhere near being high and it was not my first time smoking. I really don't think there is any relation..but idk

In the past I've had high blood pressure that the doctors couldn't explain for someone my age and health and recently at a blood donation center I was told my pulse was over 100 and was deferred from donating blood.

Today I feel fine...so I guess I'm wondering what happened to me? I feel silly even thinking I could have had a heart attack while I'm so young.. And is it even worth going to the doctor or am I just overreacting?

Sorry for the long post & Thanks for any feedback
