Differentiation of ventricular and supraventricular tachycardias based on the analysis of the first postpacing interval after sequential anti-tachycardia pacing in implantable cardioverter-defibrillator patients

Analysis of FPPIV after ATP discriminates ICD-detected T. Successive bursts (of ATP) trains at 91% of tachycardia cycle length are safe, despite being delivered before rhythm classification.
