Yes : If you are severely dehydrated or deconditioned (out of shape), your heart rate can quickly go up on treadmill test. You could still have normal heart. However, it does predict you will have higher risk of heart disease just the fact your heart rate went up quickly to maximum with minimal exertion. Answer would be to start regular aerobic exercise (fast walking, running, jogging, swimming, cycling

Yes: If you reach your target quickly it means you are not conditioned. You need to exercise more and build up your endurance. Marathon runners never reach their "target."

No: A normal heart rate is between 60--100. Above 100 is tachycardia and below 60 is bradycardia. With that being said, a fast heart rate is normal if exercising and a slow heart rate is normal if sleeping.
