I recently had a physical test in which we all had to wear a belt which would estimate our pulse. Before any warm up or anything I had a 145-150 pulse whilst having done nothing and just sitting down, and the rest had a pulse of 80-100. I have asthma, but is that a reason enough for my resting pulse to be so high? I play sports a lot and it's not really a problem but seeing that made me google and what i found was that i should be worried and go to a doctor about my heart. Can asthma be a big enough reason (i dont have trouble breathing, all i feel about my asthma is that I also have exercise-induced asthma.
