# Slow recovery of the maximal rate of rise ( $$\dot V_{max}$$ ) of the action potential in sheep cardiac Purkinje fibers

• Published 1982 in Pflügers Archiv

#### Abstract

Measurements of the maximal rate of rise ( $$\dot V_{\max }$$ ) of the action potential in cardiac Purkinje fibers were made at different intervals following an action potential or a long-duration depolarization. Recovery of $$\dot V_{\max }$$ is fast after a short depolarization but is composed of a fast phase and a very slow phase (time constant order… (More)
