My heart was beating fast

So I noticed my heart would be beating fast even though I would only be laying in bed. So I did what everyone does when they want to self diagnose themselves. I searched on Google, found out I could be having a heart attack, and reached out to my doctor. She wanted me to get some blood work done instead of going to hospital. I did that and found out my potassium was very low. This is what was causing my heart palpitations. So after taking potassium ? for about a week it started getting better, and eventually went away. Thankfully this was an easy fix, but it’s not going to go away. I have to have it checked every couple of months now, and every so often I have to take medication.
