About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

  • Patients who are pregnant.
  • Patient is in AF.
  • Patient with 3rd degree AV block.

Treatment and study plan

Cardiac resynchronization therapy

Procedure

Implanting device to measure delays between paced chambers in heart failure patients.

Other names: CRT

Primary outcomes

  1. 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.
