The monophasic action potentials of the intact canine heart.
Monophasic action potentials were recorded in 7 mongrel dogs, endocavitarily, from heart in situ and from the epicardial surface with open chest thus revealing the characteristic configuration of the different chambers. The duration of the monophasic action potential showed a good correlation with the cycle length, demonstrated during endocavitary electrostimulation.
