Thanks for your question on Healthcare Magic.
I can understand your concern.
Fever causes dehydration and release of pyrogens.
Pyrogens are chemicals which cause sympathetic stimulation. And this causes tachycardia.
Dehydration further increases heart rate.
So dehydration and pyrogens caused tachycardia in your case.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
