Key result
Bilateral stellate ganglionectomy in rats shortens action potential duration, flattens the restitution curve, and increases the maximum dominant frequency and spatial complexity of VF.
Why the study?
Does bilateral stellate ganglionectomy alter the electrophysiological properties and VF dynamics in a rat heart model?
Does bilateral stellate ganglionectomy alter the electrophysiological properties and VF dynamics in a rat heart model?
Bilateral stellate ganglionectomy in rats alters cardiac electrophysiology and VF dynamics, with effects more similar to esmolol than atenolol, highlighting the specific impact of cardiac sympathetic denervation.

Sympathetic denervation alters VF dynamics in rat models; leaves open clinical translation and requires in vivo human validation.
Xie et al. (2011) studied Cardiac sympathetic denervation. Bilateral stellate ganglionectomy (SGX) vs. Sham surgery was evaluated on Electrophysiological property changes including action potential duration and ventricular fibrillation dynamics. Bilateral stellate ganglionectomy in rats shortens action potential duration, flattens the restitution curve, and increases the maximum dominant frequency and spatial complexity of VF.
