Key result
Catheter ablation cures LVOT wide QRS tachycardia after temporary suppression by ATP and verapamil.
Why the study?
Idiopathic wide QRS complex tachycardia with responsiveness to both ATP and verapamil requires detailed diagnosis and management strategies in patients without structural heart disease.
Population
A 38-year-old female with frequent palpitations and no structural heart disease
Comparison
Response to ATP and verapamil followed by catheter ablation

May support verapamil in ATP-responsive LVOT VT; hypothesis-generating and should not yet change practice.
Case Report (n=1)
Idiopathic left ventricular outflow tract ventricular tachycardia can present as a wide QRS complex tachycardia responsive to ATP and verapamil, and is effectively treated with catheter ablation.
Mitsuhiro Nishizaki (2012) conducted a case report in Wide QRS complex tachycardia (idiopathic ventricular tachycardia) (n=1). ATP, verapamil, and catheter ablation was evaluated on Elimination of tachycardia. In a 38-year-old female, wide QRS complex tachycardia originating from the left ventricular outflow tract was temporarily suppressed by ATP, eliminated by verapamil, and cured by catheter ablation.
