Voltage-sensitive dyes (VSDs) are used to record transient potential changes in various cardiac preparations. In our laboratory, action potentials have been recorded by optical probe using di-4-ANEPPS. In this study, the effects of two different ways

Voltage-sensitive dyes (VSDpsilas) undergo changes in their electronic structure, and consequently their fluorescence spectra, in response to changes in the surrounding electric field and are therefore used for recording of monophasic action potentia

The aim of this study is to learn more about influence of the voltage sensitive dye to the tissue during optical mapping experiments on isolated animal hearts. There were recordings from all phases of the experiment examined to exclude possible negat
