    I've been taking lessons with a temporary coach that likes to do intense, non-stop drilling. Literally 15 straight minutes of forehands and backhands in a 5 ball sequence. Of course, my heart is absolutely pounding, but weird thing is I don't feel muscle fatigue. My legs and arms don't burn, but my heart's about to jump out of my chest.

    Is it normal that I only feel the effects in my heart because whenever I do intense cardio (insanity), I definitely feel the burn?

    It could be normal if you're cardiovascularly deconditioned and will get better over time with consistent training. Or it could be abnormal and a sign of ischemic heart disease.

    If you're really worried your best bet would probably be to see your doctor who will take a thorough history, examination, and measure your blood cholesterol.

    Can you measure your pulse? You can take your pulse as described on the internet. Heart monitors with wrist watch indicators usually require a chest strap but maybe there are ones that don't now. I just bought a small finger meter that measures both blood oxygen and pulse rate, very nice unit. http://tt.tennis-warehouse.com/showthread.php?t=468352

    If you have access to a gym with stationary bike or ellipticals that have pulse monitors, it would be instructive for you to see how pace and time affects your pulse.

    Maximum heart rate vs age. See approximate formulas, 220-age or 208 − (0.7 × age), etc. .
    http://en.wikipedia.org/wiki/Heart_rate

    I don't understand VO2 stuff that well. I believe it is a measure of what your heart and lungs can sustain as a maximum effort. I took a VO2 max. test. As I understand it, you can only output so much power in equilibrium depending on your lung and heart functions. In my case, I believe that the max power measured 175 watts. Athletes might be 225 watts, but research that point if interested. http://en.wikipedia.org/wiki/VO2_max

    To test it you are on a stationary bike with instruments. The test takes several minutes, it's not a sprint. They measure your oxygen intake at a given pedal resistance and rotation rate. Then they increase the resistance in steps. At first, it is easy to pedal. Then it gets more difficult. Finally they reach a step resistance where the respiration and heart rate cannot sustain the resistance on the pedals. The test ends.

    At the end, the lungs and heart cannot sustain the power output for more than, say, 1 minute. The pulse rate is really high and things are uncomfortable. It might have been my legs that were most uncomfortable. ? At 175 watts, I did well for somebody with my degree of asthma.

    After taking this test, I had a clear idea of what would happen if I attempted to sustain such a pace over minutes. My heart would beat very fast and I would become increasing uncomfortable and not be able to sustain the pace.

    VO2 max. can be increased somewhat by training.

    I once had a friend whose heart would race, not necessarily at times of maximum effort, but, for example, when he was warming up. This is not normal. There were several well-known possible causes and he was tested for them. I don't think that they were able to diagnose the cause of his rapid heart beat at that time.

    I knew one young 'instructor' who liked to wear out his young students with wind sprints around the court before the lessons. He did not understand heart rate issues and the effects that they might have on some people.
