Longer action potentials in
his contractile myocardial
cells
Faster depolarization of
his contractile myocardial
cells
YES
His contractile myocardial
cells will have a lower
resting membrane
potential
Shorter action potentials
in his contractile
myocardial cells
Larger magnitude of
depolarization in his
