Official title

Pivotal Clinical Study of VDI's Ultra-High Frequency Electrocardiogram (UHF-ECG) for the Diagnosis of Ventricular Electrical Dyssynchrony (VED): THE SYNC Study

Overview

The purpose of this study is to demonstrate the safety and effectiveness of the VDI UHF-ECG System in the diagnosis of ventricular dyssynchrony when compared to the 12-lead ECG in patients with bradycardia and heart failure indicated for pacemaker implantation.

Interventions

  • Device Ultra High Frequency Electrocardiogram (UHF-ECG)
    Electrocardiograms used on participants scheduled to undergo pacemaker implantation for bradycardia and/or heart failure.

Primary outcome measures

  • Predictive agreement between UHF-ECG and standard ECG [Time frame: Pre-procedure]
Secondary outcome measures (1)
  • Predictive agreement in dyssynchrony between UHF-ECG and standard ECG [Time frame: Pre-procedure]

Eligibility criteria

Inclusion criteria

  • Adults with bradycardia or heart failure scheduled for first time pacemaker implant (including CRT/CSP) with one of the following: Bradycardia with ventricular synchrony and QRS duration <= 110 ms, Bradycardia with LBBB, Bradycardia with RBBB, Bradycardia with other IVCD necessitating intervention, or Heart failure with LBBB
  • Understands the nature of the study and is willing to comply with all study requirements.
  • Provides written informed consent.
  • A negative pregnancy test prior to the procedure for participants of child-bearing potential.

Exclusion criteria

  • Complete AV block (3rd-degree AV block) without a stable escape rhythm or other circumstances where there is no measurable QRS.
  • Subjects with a previous or current pacemaker or defibrillator implant.
  • Anatomical or other conditions that may make a 12-lead ECG difficult to obtain, such as an allergy to components of the ECG pads, burns, open wounds, etc.
  • Currently enrolled in another investigational device or drug trial that has not completed the active treatment phase and/or would conflict with this study.
  • Other co-morbid condition(s) that could limit the participant's ability to participate in the study or to comply with study requirements or impact the scientific integrity of the study.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
