I should have asked you yesterday what is your friend's normal pulse and does she take it frequently?
Some people are normal in the 90's and have been cleared by cardiologists.
The normal heart rate in the average adult ranges from 60–100 beats/min. Intake of nicotine, caffeine may also cause increase in heartrates.
Anxiety and panic attacks can increase heartrates but some people do not have the faster heart rates with the attacks.
