Label the following as characteristic of contractile cells, pacemaker cells, both, or neither. Have calcium plateau Control rate rather than force of contraction Have sodium action potentials Do not have stable resting potential Repolarized by potassium efflux Resting Vm is near Ek+ Trace the pathway of electrical conduction in the heart but putting these events in order: Purkinje fibers depolarize Signal converges on AV node SA node cells depolarize Ventricular contractile cells depolarize Funny channels open Signal spreads through internodal pathways to atrial cells Depolarization spreads down bundle to bundle branches
