I was just updating my medications and for some reason there is a type of Tachicardia listed so I was trying to research it. I have had a rapid heart rate for the last 15 years - it started when I became addicted to pain medication. I only take 1 heart medication but 2 conditions are listed so I was just trying to understand them to know which one to delete. Forgive my slow response please. I am disabled (I think from the combination of drugs I took years ago) and so my typing is slow.
