This whole idea of getting to a fast heart rate right before the dive is new to me. I have always focused on achieving max relaxation and low heart rate right up to the last breath. Pranayama and such has helped me kick in the dive reflex, but I haven't used anything other than relaxed breathing right before the dive.

So, what are some tips and techniques for staying relaxed but cranking up your heart rate right before a dive? Also how fast can your heart rate drop once you actually go under? Seems like it could negate the effect if your heart beats fast at the beginning of the dive.
