About this study

Official title: Comparison of Cardiac Resynchronisation Therapy (CRT) Response Using High Frequency (HF) - ECG or Q-LV Guided Optimisation for Left Ventricular, Pacing Site

The research aims to compare the response of Cardiac Resynchronisation Therapy (CRT) using HF ECG guided or the conventional method of Q-LV measurement guided optimisation for left ventricular, pacing site.

Read the detailed description

The study aims to demonstrate that left ventricular (LV) pacing site optimisation using high frequency (HF) ECG improves LV reverse remodeling response to Cardiac Resynchronization Therapy (CRT), compared with Q-LV (Q-wave on the surface ECG to LV Electrogram) measurement after 6 months of treatment.

Participants will be implanted with a Cardiac Resynchronisation Therapy device with either pacemaker or defibrillator function.

The study is a single-Centre, randomized, prospective trial. One hundred and eighty participants will be assigned to either the treatment (HF-ECG guided LV pacing site optimisation) or control (Q-LV guided LV pacing site optimisation) arm, employing a 1:1 randomization. The participants will be followed up for a period of 6 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High Frequency ECG MappingOther

    A high frequency ECG map will be performed to assess the optimum left ventricular pacing site.

  • Q-LV MeasurementOther

    Measurement of Q wave on 12 lead ECG to LV stimulus to assess optimum left ventricular pacing site.

Questions about this trial

What is this clinical trial studying?

A study testing High Frequency ECG Mapping and Q-LV Measurement in people with Heart Failure, run by University Hospital Birmingham at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 21 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jamie Walton, Bsc (01213712535, jamie.walton@uhb.nhs.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Left Ventricular Reverse Remodelling (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2024; AzTrials last refreshed its copy on 31 Oct 2026.
