Numerous studies suggest the therapeutic benefit of autonomic neuromodulation to reduce cardiac sympathetic input in patients with ventricular tachycardia storm.1 Neuromodulation includes local blockade of the left stellate ganglion, a significant source of cardiac sympathetic innervation.2 Transcutaneous magnetic stimulation (TCMS) has a role in noninvasive and nondestructive modulation of nervous system activity.3,4 Animal studies have demonstrated the ability of magnetic stimulation to modify arrhythmias by targeting cardiac sympathetic innervation.5,6 In this study, the first of its type involving human participants to our knowledge, we investigated the feasibility and adverse events of TCMS for left stellate ganglion inhibition in ventricular tachycardia storm.
