Visualization of cardiac action potential wave propagation by fluorescent imaging

Abstract

Although implantable cardioverter defibrillator (ICD) therapy is a well-established therapy for treating patients with sudden cardiac disease, ways to optimize this therapy has been basically empirical. Fluorescent optical mapping system offers ways to visualize the cardiac electric activity during electric shocking. Software applications were developed with Matlab/Labview to facilitate people with limited computer knowledge to analyze the cardiac action potential wave propagation data.
