Cardiac optical mapping with voltage-sensitive dyes has become an important tool for studying the electrophysiology of the heart. Excitation with the appropriate light source and detection by a photodiode array or charge-coupled device video camera would produce an optical map that allows the visualization of action potentials and evaluation of wave propagation. |
Conduction VelocityBecause optical mapping allows the construction of a visual map of conduction velocity, it is a very useful tool in studying conduction heterogeneity and cardiac arrhythmias.

Measure ArrhythmiaCardiac optical mapping has also helped to enhance understanding of electrophysiological remodeling in disease states, as well as the development of diagnosis and treatment of cardiac disease

InhomogeneityWith optical mapping, Inhomogeneity in conduction can be quantified using the activation times obtained by a high-density mapping system, and the abnormal conduction pattern of the heart can be better captured.
