Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- You are 18 years old or older and have a permanent irregular heart rhythm (called atrial fibrillation) along with a heart that pumps less efficiently than normal (less than 50% of its capacity)
- You either need electrical pacing to keep your heart from beating too slowly (including if you are having a procedure to block the heart's electrical connection), or your doctor has recommended a special type of pacemaker that helps both sides of the heart work together (called cardiac resynchronization therapy)
- It is expected that your pacemaker will need to actively pace your heart more than 40% of the time
- You have been on optimized heart failure medications for at least 3 months
- You already have a heart device but need it upgraded to a cardiac resynchronization therapy device (you may still be eligible)
Who may not be able to join:
- You are under 18 years old
- You are pregnant or are actively trying to become pregnant
- You are not able to have the required pacemaker leads (wires) implanted in the necessary locations in your heart (confirm with trial site)
- You have had a heart valve procedure, heart valve surgery, or a heart attack within the last 6 months
- You have the most severe stage of heart failure (where you are severely limited even at rest), or you currently have a mechanical heart pump implanted, or you have had a heart transplant
