Random rapid heart rate tapering off of prednisone?

Posted by valesp @valesp, Nov 21, 2025

I started taking prednisone December 2024 20mg. I just tapered down to zero two weeks ago. I noticed about the last 3-4 months I seem to have random rapid heart racing even while resting. Sometime several times a day but not everyday. Anyone else experiencing this? My Dr. wants to put me on a heart monitor for a week.

You may just need magnesium supplements. I had several episodes of rapid and fluxuating heart, and did an Afib test on my Apple watch, which showed I did have Afib. I started taking Magnesium and it hasn't happened again. I take Magnesium Theronate in the morning and Magnesium Gycinate in the evenings ever day. Most people are deficient in magnesium.
