Enhanced Diagnosis of Ventricular Activation Pattern Using Intracardiac Electrograms

Enhanced Diagnosis of Ventricular Activation Pattern Using Intracardiac Electrograms

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.

Inclusion Criteria:

• Patient with SJM CRM device implanted for more than 90 days

Exclusion Criteria:

• Suspicion of lead dislodgment
