Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Presently, the left ventricular lead is placed in a similar position for all patients. It is not known whether placing this lead in different positions in the heart will make the heart pump better. In this study, the investigator will collect measurements of the heart's electrical activity during an Electrophysiology Study (EP study or EPS). The hope is that these measurements will provide the know how to develop an individualized left ventricular lead placement "prescription" for patients referred for left ventricular lead pacing.
