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.
Interventions
PROCEDURELV 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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation of ventricular activation patterns determined by 12-lead ECG and device IEGMs-based method | Acute, intraoperative | Correlation coefficient between ventricular activation patterns determined by a traditional technique, 12-lead ECG based vs. device based IEGMs method. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Ventricular activation origin location determined by IEGMs based method vs. by detailed mapping | 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 |
