Heart rate issues

Is anyone else’s heart rate jumping really high. Mine has been. It’s been bad today. At one point just from walking up my steps it shot up to 124 bpm. It doesn’t last all day but I get out of breath and can feel my heart if I carrie heavy stuff or go up and down my steps a few times. I understand it’s going to stay a little higher then normal. It has been since I found out (Saturday) around 90-95 bpm. If any one has any in put I’d appreciate it. I’m just scared, I don’t want to lose this too. So I’m looking at everything. Thank you ladies
