I wouldn't assume that. The male Nurse who treated me in the hospital was a former Army medic and had spent lots of duty time over in the sandbox. He told me a bunch of stories about guys over there going down hard from dehydration and having a-fib, seizures, etc. He was the one that figured out quickly that it was dehydration. He took one look at me and said "You look dry." jabbed an I.V. in me and it was all fixed by the time the cardiologist showed up.
