Talk to General Physician on Irregular Heartbeats

السلام علیکم

I have a concern regarding my heart rate.

My height is 5'4 Weight is 77kg

Also, im over weight from childhood. I've been to gym, lost weight but again when I left the gym I again started gaining weight (been a year now)

Question : I've a continuous irregular heartbeat that remains between 95-110. Regardless, if I m sitting or haven't done any major tiring work, whenever I check heartbeats are high. I don't have short breathe issue, although I'm a regular smoker. Should I worry about it or that is fine?
