Case Report (n=1)
The mechanism and origin of VT storm can offer diagnostic clues for masked cardiac ischaemia and the culprit artery, which can be successfully treated with reperfusion and targeted catheter ablation.
Itoh et al. (2022) conducted a case report in Incessant wide QRS complex tachycardia refractory to amiodarone (n=1). Catheter ablation was evaluated on Freedom from electrical storm. Catheter ablation targeting Purkinje-related premature ventricular beats successfully eliminated electrical storm without the need for antiarrhythmic drugs.
