Enhanced Diagnosis of Ventricular Activation Pattern Using Intracardiac Electrograms

Not Applicable
Completed
Conditions
Arrythmia
Interventions
Procedure: LV pacing site
Registration Number
NCT02057588
Lead Sponsor
Abbott Medical Devices
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.

Primary Outcome Measures
NameTimeMethod
Correlation of ventricular activation patterns determined by 12-lead ECG and device IEGMs-based methodAcute, intraoperative

Correlation coefficient between ventricular activation patterns determined by a traditional technique, 12-lead ECG based vs. device based IEGMs method.

Secondary Outcome Measures
NameTimeMethod
Ventricular activation origin location determined by IEGMs based method vs. by detailed mappingAcute, 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
