Question

Ian, Tillingham asked:

Iím approaching retirement and I have a high heart rate (up to 195bpm when Iím really working hard), I do quite a lot of training, so is this normal?

Answer

There are lots of things that can increase your heart rate, such as drinking caffeinated drinks or alcohol, or even having an heated argument!  The heart should match the beat rate to the demands of your body, so that the right amount of blood gets pumped.  If you pump too little blood your tissues become starved, but if you pump too much youíre wasting energy.  There are some medical conditions that can make the heart pump too fast, but usually they donít cause the heart to go fast all the time.

Itís hard to say whatís a Ďnormalí heart rate, as diet and level of fitness can really make a big difference.
