New ECG method to predict CRT benefit in heart failure
Part of Heart & circulation clinical trials.
This trial tests a new way to use an ECG (electrical heart recording) to predict who will benefit from a special pacemaker called cardiac resynchronization therapy (CRT). It is for people with heart failure and a specific heart rhythm problem.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have heart failure from blocked arteries or other heart muscle disease.
- You have symptoms like shortness of breath or fatigue with activity or at rest (NYHA class II to IV).
- Your heart's pumping strength (left ventricle ejection fraction) is 40% or less.
- An ECG shows your heart's electrical signal is wider than 130 milliseconds (wide QRS).
- You have a specific type of electrical block called 'left bundle branch block' (LBBB), confirmed by a special heart test.

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 study compares different ways of pacing the heart to improve its pumping ability in people with heart failure. It aims to find the best pacing method to help your heart work more efficiently and improve symptoms.
This trial tests a noninvasive way to map your heart’s wiring and veins to help guide placement of a heart resynchronization therapy (CRT) device. If you have certain abnormal heart rhythm and weak heart pumping, it may help doctors place the therapy more accurately and safely.
This trial looks at how well an echocardiogram (ultrasound of the heart) can predict outcomes for people with left bundle branch block who already have cardiac resynchronisation therapy (CRT). If you qualify, your heart scans may be used to better estimate risk and guide care.
This study is testing a portable heart monitoring device to help doctors check how well a special pacemaker (LBBAP) is working. It may help people who need a new or upgraded pacemaker or heart device.
This study tests a new way to place a heart device lead to help the heart beat in sync for people with heart failure and a specific abnormal heart rhythm. The goal is to see if this method improves outcomes compared with standard treatment.
