Recurrence of tako-tsubo syndrome, idiopathic dilated cardiomyopathy, and iterative ventricular tachycardia: just a fortuitous coincidence or a pathophysiological link?

We hypothesize that the pathophysiological link among these clinical conditions could be the hyperactivity of the sympathetic nervous system.
