Brief Summary:
The objective of this study will be to evaluate the ability of IEGMs (Signal recorded from implanted pacing leads) and pseudo ECGs (derived from various IEGMs) to characterize various electrical conduction patterns. Electroanatomic mapping data and 12 Lead ECG will also be collected to characterize electrical conduction patterns during standard electrophysiology exam.

Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Enhanced Diagnosis of Ventricular Activation Pattern Using Intracardiac Electrograms
Study Start Date : February 2014
Actual Primary Completion Date : June 2016

Arm Intervention/treatment
LV Paced sites
LV pacing sites : Patients will be paced from various left ventricular origin, defined by their 3D localization.
Procedure: LV pacing site
Patient will be paced in VVI mode from Left ventricle specific position for a short period of time per position in order to cover spontaneous ventricular activity




Primary Outcome Measures :
  1. Correlation of ventricular activation patterns determined by 12-lead ECG and device IEGMs-based method [ Time Frame: Acute, intraoperative ]
    Correlation coefficient between ventricular activation patterns determined by a traditional technique, 12-lead ECG based vs. device based IEGMs method.


Secondary Outcome Measures :
  1. Ventricular activation origin location determined by IEGMs based method vs. by detailed mapping [ Time Frame: Acute, intraoperative ]
    Use of available IEGMs recorded on implanted device to discriminate specific VT origin and pattern and compare the results to the detailed mapping data
