His baroceptors did not compensate adequately and he experienced a transient drop in cranial blood pressure that resulted in a brief loss of consciousness from which he recovered quickly and with out further sequelae. I didn't get the impression that he is walking around fainting for no reason. This happens to me frequently,w/o loss of consciousness, pretty frequently. I'm healthy, and I deal with it.
