Overview
Brief Summary
This study is an effort to use left ventricular (LV) lead based measurements to identify late electrical activation and avoid scar.
Detailed Description
The aim of this study is to characterize how right ventricular (RV) to left ventricular (LV) conduction delays are altered by pacing site in patients with a cardiac resynchronization therapy (CRT) system. The study will be performed in conjunction with a CRT implant.

Eligibility Criteria
Inclusion Criteria
- •Patient is greater than 18 years of age.
- •The patient or the patient's legally authorized representative is willing to give informed consent.
- •CRT indicated guidelines.
- •Patient is receiving a Medtronic IPG or ICD.
Exclusion Criteria

Outcomes
Primary Outcomes
Measure how RV to LV conduction times are altered by pacing site in patients with a CRT system.
Time Frame: 30 minutes
This procedure will take approximately 30 minutes prior to implant of a CRT system. At completion of this study the patient is not followed and will be transferred to another study if enrolled in a clinical or followed as a routine implant by the center.
