Does caffeine raise your heart rate?

Coffee and Green tea seem to do the trick. I can usually feel it. I get jittery with coffee too. I remember having a can of that Starbucks Doubleshot before one of my classes and I couldn't sit still. I didn't really want to pay attention either because my mind kept drifting off.

I guess I'm a coffee lightweight?

I guess that's better than being an addict who requires a cup every 2 hours.
 
Coffee doesn't but energy drinks sure do. They make it feel like my heart wants to jump out of my chest.
 
Mine specifically or just as a general physiological response when a human being ingests caffeine? Because in both cases, I believe the answer is "yes."
 
Caffeine can increase your heart rate, yeah. Those jitters you mentioned are, in some cases, precursors and/or early symptoms of "caffeinism" and possible caffeine intoxication...although unless it was a HUGE cup of coffee you drank, it probably wasn't the latter.
 
i gave up soda and a lot of other caffeinated beverages a few years back so if i have a coffee or an energy drink it gets my heart going like the clappers. pretty much i cant have one after about 4-5 o'clock or i'll be restless all through the night.

same here.
 
I haven't paid attention to rate, but it seems to raise my blood pressure by a good 10pts (both measurements) if I have 2-3 cups worth.
 
Nope. I can drink a monster or a few vaults or some mountain dew or a big mug of coffee, doesn't matter, absolutely nothing changes. I can go to bed right afterwards too.
