Hello,
There is nothing wrong with a rapid pulse after exertion and this is normal. However any chest or neck pain/ discomfort on exertion needs to be evaluated to rule out heart disease. This can be done by an exercise stress test in a cardiologist's office. A normal stress test would be reassuring.
Regards.
