Cardiac Innervation and the Autonomic Nervous System in Sudden Cardiac Death

Publication date: December 2017 Source:Cardiac Electrophysiology Clinics, Volume 9, Issue 4 Author(s): William A. Huang, Noel G. Boyle, Marmar VaseghiTeaser Neural remodeling in the autonomic nervous system contributes to sudden cardiac death. The fabric of cardiac excitability and propagation is controlled by autonomic innervation. Heart disease predisposes to malignant ventricular arrhythmias by causing neural remodeling at the level of the myocardium, the intrinsic cardiac ganglia, extracardiac intrathoracic sympathetic ganglia, extrathoracic ganglia, spinal cord, and the brainstem, as well as the higher centers and the cortex. Therapeutic strategies at each of these levels aim to restore the balance between the sympathetic and parasympathetic branches. Understanding this complex neural network will provide important therapeutic insights into the treatment of sudden cardiac death.
