Caffeine and heart weirdness

Hi,

So, for the past year I’ve been in the habit of drinking a energy drink everyday (Bang or Reign) and recently I’ve noticed some weird heart behavior. After I drink my energy drink around noon everyday, about three times throughout the day I’ll get a feeling that my heart skips a beat and I push a small amount of air out of my lungs. It almost feels like I get the wind knocked out of me for a quarter of a second. Is this something I should be worried about? I’m 22, pretty active, and only drink 300mg of caffeine a day and don’t have any other issues. I look forward to my daily energy drink and I think I have a pretty good tolerance to caffeine. Should I stop drinking them?

Thanks.​
