Hello, welcome to Justanswer, I will try to assist you with your medical question, and any medical information you seek
When you had the irregularity, was your heart racing?
steady beat and then skipped beats, back to regular beats for a sort time and then back to fast irregular beats
As long as the beats are not rapid, and you don't have any shortness of breath, dizziness or faint feelings, it is not an emergency, and can wait until the next day, but if you notice a rapid thready pulse, then you need to go to an ER right away
the fast, irregular beats suck the breathe down, from my throat
Those are indicators that you need to go to an ER
