Mechanisms of Ventricular Arrhythmias in Acquired Heart Disease

Description

This session will discuss elements of structural and functional remodeling in structural heart disease and how these contribute to ventricular arrhythmia mechanisms.

Learning Objectives

Describe the different elements of ventricular arrhythmia mechanisms.
Consider translational possibilities for mechanistic information in development of new ventricular tachyarrhythmia therapies.
Summarize limitations of current ventricular arrhythmia treatment options.
