The site of gating in the ventricular conducting system of rabbit, dog and monkey hearts.
The longest action potential durations of the ventricular conducting system were found at about two thirds of the distance along each false tendon in dog and monkey hearts. In the rabbit heart, this area which corresponds to the gating mechanism - was found in the middle part of the bundle branches; therefore the number of gates is much smaller in the rabbit than in other 2 species.
