Who might be able to join this trial:
- People who are willing to participate and have signed a consent form agreeing to take part in the study.
- People who are 18 years of age or older.
- People who have a specific heart electrical conduction problem called left bundle branch block, with certain measurements of their heart's electrical activity (QRS ≥130ms) and reduced heart pumping function (heart pumping at 35% or less), and who do not need a pacemaker for a separate heart rhythm problem called AV block.
- People who have a heart electrical conduction problem other than left bundle branch block, with certain electrical activity measurements (QRS ≥150ms) and reduced heart pumping function (heart pumping at 35% or less).
- People who have reduced heart pumping function (less than 40%) and who do need a pacemaker for an AV block condition, where resynchronisation therapy (a type of specialised pacemaker treatment) has been recommended.
- People who have significantly reduced heart pumping function (35% or less), are experiencing severe heart failure symptoms (classified as NYHA class III or IV), have an irregular heart rhythm called atrial fibrillation, have certain electrical activity measurements (QRS ≥130ms), and where a plan is in place to ensure the heart is being properly paced on both sides (confirm with trial site).
Who may not be able to join:
- People who have had a heart attack, unstable chest pain, or a procedure to restore blood flow to the heart (such as a stent or bypass surgery) within the past 3 months.
- People who are pregnant.
- People who are currently enrolled in another clinical trial that involves an active treatment.
