Welcome aboard. If you don't mind me asking-being snoopy-what work up have you had beyond the two day event monitor? Next questions are you scheduled with a cardiologist? Or perhaps you were. On this site you will find many different heart events happening and so many wonderful people sharing and offering encouragement. Me, personally, I was dealing with bradycardia which required a pacemaker. I am not a coffee person so I can't say that was my trigger. I had 6 second pauses register on a 30 day event monitor that required more investigating. I have a strong heart just not a consistent normal sinus rhythm but then I was found to have junctional node rhythm decades ago that didn't represent itself to be a serious concern-now I am not so sure. But then the PM has been an important component for me. Here's to hoping the "mystery" gets resolved for you.
