Paper Abstract

An important effect of electrical stimulation on myocardial tissue is the change in the transmembrane voltage induced during the stimulation pulse. This initial effect then activates transmembrane voltage-dependent ion channels and can produce a propagated action potential after the pulse. Fluorescence mapping with transmembrane voltage-sensitive dye has been used to measure the direction of the initial change in transmembrane voltage-sensitive during a stimulation pulse and the magnitude of the change relative to the action potential amplitude.
