I have premature irregular heart beats . it's skipping hard when i take a deep breath in everytime. why? could it be bc i had half a coke cola?

Avoid triggers: Skipped beats usually imply premature ventricular or atrial contractions (pvcs or pac's). They are triggered by Adrenalin surges or stimulant effects (caffeine/alcohol/meds can trigger). Pain/breathing issues/physiologic stress can trigger as well. In the setting of anormal heart structurally these symptoms are more of a nuisance than a danger. Void the triggers.
