Hi Terry

None - the heart is quite happy to beat at 200 beats per minute. The problem is often that the rest of the body is not, and you can't really sustain that kind of intensity for very long - a few minutes is about the limit for most people.

There is one exception to this, and it's important - people who are at risk of heart attack, who have high blood pressure, or previous heart attack, for example, are advised to keep their heart rate down. Severe shortness of breath, chest pain, arm pain - all are signals of risk, so pay attention to them. Also, if your heart rate is that high but you're not actually training hard, then it's a sign of something and you may want to consider an ECG to ensure that there are no underlying cardiac problems.

But if you're healthy and fit and have been cleared of that risk, then your heart is not limiting at all. So you need not worry if it is up near your maximum.
