Checking heart resynchronization timing with a noninvasive test
Part of Heart & circulation clinical trials.
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are being evaluated at Oslo University Hospital for CRT (before implantation or after as follow-up).
- Your heart rhythm is sinus rhythm.
- You have heart failure symptoms classified as NYHA class II or III despite best medicines.
- You have left bundle branch block and your QRS duration is at least 130 ms (a heart tracing measure).
- Your heart pumping strength (left ventricular ejection fraction) is 40% or less, and you had an echocardiogram before implantation.
- You are between 18 and 80 years old, and you can give informed consent.

This study looks at whether a device called CRT (Cardiac Resynchronization Therapy) can help people with heart failure who have a weak heart pumping strength and a “wide” electrical signal pattern on an ECG. It may help some people feel better and improve heart function, especially if they are not already on the best standard medicines.
This study tests a new heart scan method to help doctors place pacemakers more accurately for people with heart failure. It aims to improve the effectiveness of the pacemaker treatment and may lead to better outcomes for patients.
This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
This trial tests a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
This trial compares two types of pacemaker placement to improve heart function in people with heart failure. One method paces the heart's natural conduction system, while the other paces the lower chambers of the heart. The goal is to find which approach works better for heart resynchronization therapy.
This study measures how well blood flows in the heart (coronary flow) in people with heart failure with reduced pumping strength and a specific heart rhythm problem called left bundle branch block. It focuses on people who already have a cardiac resynchronization therapy (CRT) device and have stable treatment, to see how coronary flow relates to their heart condition.
