If you have a rapid heart rate and unexplained shivering when you are sick, is that dehydration or is that fever?

Maybe both: That may be a result of both fever and dehydration. Fever, left untreated, will result in dehydration and they both (fever and dehydration) lead to tachycardia (rapid heart rate).
