Your monitors would have likely picked up if it was afib. Stress and anxiety are likely contributors but also consider tending to any indigestion or acid reflux. Stomach issues can be a big trigger for premature beats. Simple gas can trigger one due to it's proximity to the vagus nerve. So watch foods that cause gas or indigestion and see if that helps.
Thank you for the response. It helps me realize that I'm just having skipped beats and not Afib. Thanks again and take care.
Skipped beats still feel regular, your heart goes like beat, beat, pause, beat, beat. Afib your heart beat is extremely irregular, no rhyme or reason to how it's beating. It speeds up, slows down, speeds up, you feel dizzy and even on beta blockers when I have an episode by pulse rate is usually 140-160.
