Throw that shit in the trash. Do it, right now. If you have health anxiety like me, then you've checked your heart rate more times than anyone ever should. You're not in aFib, you're not in cardiac arrest, you're not having a heart attack. 

I purchased everything. Smart watch, at-home EKG, blood pressure cuff, all of it. I went to the ER last week thinking I was having a heart issue and had every test come back perfect. Verbatim I heard "the likelihood of you having a cardiac event in the next 30 years is next to zero." Even though I got that, I went home and obsessed over my heart rate. It was low. How could it be low when I lost sleep, and was so stressed? It took my therapist reminding me that I've lost over 100 lbs in the last few years and that the very thing I was working for (healthier heart) was happening. Low resting heart rate, decent BP, and a heart that rests quickly.

For a normal person, there's nothing wrong with having something that can warn you of a _**potential**_ problem that you should bring up to your doc. For those of us with health anxiety though, we'll take that one notification as absolute truth. Listen to your docs, they generally don't like sending patients away that have the potential to drop dead.
