Paper Abstract

Voltage-sensitive dyes have been used to optically monitor cardiac transmembrane potential for almost twenty years. This method now permits mapping of cardiac activation and recovery with spatial resolution that is unattainable by conventional mapping techniques. Despite the growing use and potential advantages of optical mapping with voltage-sensitive dyes, little information is available regarding optical action potential signal characteristics. Thus, no accepted standards for recording optical action potentials exists (e.g., sampling rates, analog filtering requirements). This paper will review some of the unique characteristics of optically recorded cardiac action potentials.
