If it's never been done, a complete blood count (to exclude anemia, common in young women), TSH (exclude thyroid xs), and echo (exclude structural heart disease) should be done. ...Read more

If somebody has high heart rate (>90 at rest) it is very easy to hit the max HR during exercise even moderate. How safe is to exercise at that level?

If somebody has high heart rate (>90 at rest) it is very easy to hit the max HR during exercise even moderate. How safe is to exercise at that level?

Slowly increase...: Lack of conditioning can lead to a HR that increases rather quickly with exercise. Slowly increasing the duration & exertion with exercise - and being consistent with exercise will help lead to a lower resting HR and a slower increase. The max HR recommendations are safe; however, it isn't easy to maintain them for a length of time that would be beneficial. Build up your tolerance. ...Read more
