Anyone else quitting for heart reasons?

My heart rate is fine resting, but once I do any sort of physical movement my heart rate sky rockets and I do get palpitations. It also gives me major anxiety. This is the main reason I’m quitting. I also am sure it gives me gerd which causes heart issues as well. Anyone else experienced what I have? How long did it take to go away?

I’ve had a heart scan and ecg as well. Doc wasn’t concerned, but he did tell me to quit nicotine
