Sympathetic Blockade for Dysrhythmia Management in Heart Failure: Rationale and Therapeutic Progression to Intervention

Abstract

Continuous ganglionic blockade is being used increasingly to help manage ventricular tachydysrhythmias. The purpose of this chapter is to discuss the physiologic and anatomic basis of ventricular tachydysrhythmias in detail that are mediated by the sympathetic nervous system and to discuss appropriate indications for the use of sympathetic ganglion blocks. These blocks can be instituted as both destination and bridging therapeutic options to control these dysrhythmias. These blocks therefore have value in the heart failure patient population since they offer a means of controlling the dysrhythmias that can be devastating to an already compromised myocardium.
