Abstract:
Macroscopic T-wave alternans (TWA) is a rare finding on surface electrocardiogram and has been associated with an increased risk of impending sudden cardiac death. We highlight a case of macroscopic TWA in a patient with markedly prolonged QTc interval preceding ventricular electrical storm, which was refractory to medical management. Autonomic modulation of the stellate ganglion resulted in improvement in both TWA and QTc interval. (Level of Difficulty: Advanced.).

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
