Answer

Diagnostic electrophysiologic study (EPS) requires placement of electrode catheters in the ventricle, followed by programmed ventricular stimulation using progressive pacing protocols. EPS is particularly relevant in patients considered to be at high risk for sudden death as a result of significant underlying structural heart disease.
