Paced qR morphology and transition during threshold testing predicted greater improvement in LVEF, whereas RWPT lacked predictive value. Loss of terminal R in lead V1 and prolongation of RWPT on follow-up prognosticated nonresponse to LBBAP.

Here are a couple of criteria that help diagnose VT:
1) All QRS complexes in anterior precordial leads are positive
2) aVR: Q wave > 40 msec with notch in descending QRS (Vereckel algorithm).
3) R-S interval in precordial leads > 100 msec (Brugada criteria)
4) I proved it on EPS
Electromagnetic interference on an implantable defibrillator with ICD shock. The EMI came from a poorly grounded light in a swimming pool. When the person got out of the pool, the EMI disappeared. From M Akhtar, Clinical Medicine Insights. Cardiology, 24 Jul 2014, 8:63-66
