Yep. My heart-rate is normally pretty low (45bpm or so, 55 if I'm walking around), and my BP is on the high end of normal, but white-coat syndrome reliably brings it up to a fluttery 110bpm and 155/125 pressure. I was just in a wreck last week, so I got to see the before-and-after measurements from a few medical providers, and it's shocking how the act of talking to a new person in an unfamiliar environment spikes my BP even when I "know" that it's fine, and also how quickly it falls back down to normal.
