Reverse Trendelenburg Position Modulation to Induce Atrial Tachycardia During Supraventricular Tachycardia Ablation

Tachycardia induction is an essential part of supraventricular tachycardia (SVT) ablation that helps to establish the accurate diagnosis, mechanism, and location of the arrhythmia. Several approaches are typically employed to induce SVT in the electrophysiology (EP) laboratory, including drug infusion (isoproterenol, caffeine, epinephrine, adenosine, etc), pacing maneuvers (multisite pacing, extrastimuli, burst pacing), and varying the degree of sedation.1,2 We describe a case of SVT that could be induced only after altering the patient’s position via reverse Trendelenburg (RT).
