Ultra-High Frequency - Electrocardiogram (UHF-ECG) for the Diagnosis of Ventricular Electrical Dyssynchrony (VED)

Summary

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.

Eligibility

Inclusion Criteria:

* Adults with bradycardia scheduled for pacemaker implant or heart failure patients indicated for cardiac resynchronization therapy (CRT) with one of the following:

  * Bradycardia with ventricular synchrony and QRS duration \< 110 ms in men or \< 100 ms in women or;
  * Bradycardia with left bundle branch block and QRS duration \> 140 ms in men or \> 130 ms in women or;
  * Bradycardia with right bundle branch block and QRS duration \> 130 ms in men or \> 120 ms in women or;
  * Heart failure with left bundle branch block and QRS duration \> 140 ms in men or \>130 ms in women.
* 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.
