Detailed Answer:
Hello,

Welcome and thanks for your query.
These are common symptoms of anxiety as they are produced by stress hormones that are released during episodes of anxiety and panic.
These would return to normal when the anxiety / panic passes. If the symptoms persist without abating, it would be better to see a doctor, have yourself investigated for conditions like a hyperactive thyroid etc.
Take Care,

Brief Answer:
Explanation follows

Detailed Answer:
Check if your Thyroid function was tested. If not get the same done.
We have an autonomic nervous system which controls the function odf our internal organs. There are two components of this - the sympathetic and the parasympathetic. The sympathetic nervous system is the one which helped us historically when we were hunters to release sudden energy to either chase a prey or to escape from a predator. When we have an anxiety or panic episode, these neurotransmitters and hormones are released into the blood and these produce the symptoms. Parasympathetic nervous system especially the vagus works in reducing these and when they are in perfect balance, the physical symptoms usually do not occur.
If you eat a wholesome meal, exercise and practice stress relieving methods like yoa, meditation, relaxation exercises, then you would find that these episodes are less.
I don't think there is any reason for you to worry. If you are not convinced, a Holter monitoring of the heart and a pulse oximetry may be done which are likely to show no abnormality.
Best wishes,
