1 Atrioventricular hysteresis pacemaker mode promoting a short-long-short sequence at the onset of ventricular tachycardia  Neiberg de Alcantara Lima, MD, Stela Maria Vitorino Sampaio, MD, PhD, Ricardo Lessa de Castro, MD  HeartRhythm Case Reports  Volume 4, Issue 12, Pages (December 2018) DOI: /j.hrcr Copyright © 2018 Heart Rhythm Society Terms and Conditions

2 Figure 1 Pacemaker when it started the IRS-plus algorithm. Atrioventricular interval was increased from 200 ms to 400 ms, and then after 3 ventricular paces (VP) there was a premature ventricular contraction (PVC) sensed as a normal ventricular sense (VS), followed by 2 VP and another PVC sensed as a normal VS; then the patient had a ventricular safety pace, followed by another VP and a PVC. Last cycles performed a long-short-long sequence, which may have induced ventricular tachycardia. AP = atrial paced.
