Once a saint, now a sinner: An appropriate or inappropriate shock?

Abstract

Critical analysis of electrograms of any therapy delivery event is paramount to identify the etiology, specificity, and sensitivity of the programmed algorithms to differentiate supraventricular versus ventricular tachycardia, its effectiveness, and potential interventions to prevent recurrence. Besides the aspects mentioned above, this case delves into the potential limitations of existing algorithms and the adverse effects of anti-tachycardia pacing.
