Nurses out in attendance - jump heart rate give somebody the third degree?

Hey all - could anybody back me out with this? Earlier today my chest be hurting... and this evening my resting pulse has be jumping from 70 to 110, inside a minute or two sometimes. I FEEL like it's race...
My pulse is usually 45-60, which is kind of strange in itself because I've be feeling poorly for months, and not amazingly active. BP is usually 95/55, sometimes 85/45 - immediately it's 120/80. I've been fancy weak and dizzy for several months, and lower than doctor's care...
I'm a moment ago wondering, do I need to do anything tonight? Two days ago I have a bad allergic reaction to Compazine (a stomach drug) and right now I'm on Ritalin (as an upper, not for ADHD) - but I've be on this for a while. I feel considerate of shaky, and dizzy still... any ideas going on for what's wrong? Should I go contained by for immediate attention? Oh, I'm 20, and fit weight, btw.
Thanks :)Nurses out in attendance - jump heart rate give somebody the third degree?
Just step to the Doc sweetness, could well be side effects from your current meds butyou visibly have a few medical issues so a moment ago pop along to the dr much safer for you that way.
hope you have a feeling better soon!
you should tell your doctor
