Judging from the fact that you were feeling light headed, feeling tingling in your legs, and 6'2", it could be that you actually had low blood pressure. Did you feel it when you were getting up? Also, your bp's pretty much within range--it can change quite a bit depending on how wound up you are, whether you've been exerting yourself, and even the time of day so one single reading is nothing to make a diagnosis by. It'd probably help if you gave more info like any meds your taking, whether your family has had heart probs in the past, how long you've felt this way, etc. Still, going to the doctor to get it checked out can't hurt.
