How does a constrictor know when to let go?

^^^ ..Yeah.... not sure what you mean by heartbeat rather than pulse? The electrical firing of the heart..?

A pulse is the result of a heart beat.

Not exactly... If you place to fingers on your wrist or your jugular then you would be feeling pressure from the blood flow etc. If you put your hand on your chest then you would be more or less looking for vibrations from the echo.

I corrected that statement. I am trying to type while watching t.v.

Ventricular contractions create a pulse in the distal regions of the body.

Well yes, but that seems very strange to wonder if the snake can actually feel a palpable heartbeat all the way inside the chest rather than pulses closer to the surface.

I don't believe they do. At all. I think they just squeeze until they feel no more movement and then squeeze some more.

I don't believe they do anymore either but for a much simpler reason. My snakes are still constricting prey that doesn't have a heartbeat.
