Figure 1 A: Echocardiographic appearance of this patient’s left ventricular apical hypertrophy. B: Progressive electrical changes over time per surface electrocardiograms (ECGs) (N = 47). R-wave amplitude and T-wave amplitude both declined over time. Units are in mV (millimeters have been converted accordingly from each ECG’s calibration). Examples of V4 complexes are displayed on the right (R-wave reduction −37%, ST −96%).

Figure 2 Electrogram as recorded by the device at the onset of ventricular fibrillation (VF) demonstrates failure to sense VF. HeartRhythm Case Reports 2017 3, 43-48DOI: (10.1016/j.hrcr.2016.08.018) Copyright © 2016 Heart Rhythm Society Terms and Conditions

Figure 3 A: Electrograms prior to placing the right ventricular (RV) septal lead. B: Catheter placement is shown with a 20-pole mapping catheter in the right ventricle that has been advanced as distally as possible to approximate sensing at the apical lead and a 4-pole mapping catheter to approximate the high septal activity. The apical activity (DD1–2) is fractionated, low-amplitude signal during ventricular fibrillation (VF). However, the same activity is discrete and high-amplitude at the basilar RV septum. C: New RV septal lead with associated electrogram during induced VF with cleaner signal (red) as compared to the old lead (blue), also with activity during VF.
