1 Ventricular tachycardia secondary to abandoned epicardial pacemaker lead 
Chance M. Witt, MD, Samuel J. Asirvatham, MD, FHRS, Carole A. Warnes, MD, Christopher J. McLeod, MB, ChB, PhD, FHRS  HeartRhythm Case Reports  Volume 1, Issue 3, Pages (May 2015) DOI: /j.hrcr Copyright © 2015 Heart Rhythm Society Terms and Conditions

2 Figure 1 Twelve-lead Holter monitor recording showing the clinical ventricular tachycardia. HeartRhythm Case Reports 2015 1, DOI: ( /j.hrcr ) Copyright © 2015 Heart Rhythm Society Terms and Conditions

3 Figure 2 Inferior view of the heart looking specifically at the subpulmonic left ventricle. Left: Activation map showing a central early point from which activation spreads outward. Right: Electroanatomic voltage map with the scale set to 0.5–1.5 mV. As evident from the map, the earliest point and ablation lesions were delivered within an area of essentially normal myocardium with voltages >1.5 mV.
