Sympathetic innervation of the anterior left ventricular wall by the right and left stellate ganglia
Heart Rhythm, 08/09/2012
Vaseghi M et al. – Both the left stellate ganglion (LSG) and the right stellate ganglion (RSG) provide significant innervation to the anterior LV wall as demonstrated by both ARI shortening and norepinephrine (NE) concentrations. LSG stimulation significantly increases activation recovery interval (ARI) dispersion. This study provides mechanistic insight into the beneficial effects of left sympathectomy and the additional role of right sympathectomy in reducing arrhythmias in patients with anterior myocardial scars and VT storm.
