chest pains & cardiovascular exercises

[Lao Tzu]

my resting heart rate is about 95 bpm.

i have decided to use an aerobic stepper for cardiovascular work as it gets my heart rate up higher than a bike.

Yesterday, i had my heart rate up to about 190 bpm (normally, when doing cardio i top out at 160, sometimes going to 180) on the stepper for about 15 minutes when my legs got too tired. But today i am having chest pains on & off.

Is this an angina. Anyone know?

At what time did you measure your heart rate? I ask because it seems rather high; its supposed to be measured right after waking up, while you are still in bed. It goes up slightly when you are up and about.
