Cardiac Resynchronization Therapy (CRT) Pacemakers: Getting the Heart Back in Sync
When your heart’s chambers don’t beat in unison, it can affect how efficiently your heart pumps blood. For some people, this leads to heart failure or worsening symptoms of an already weakened heart. That’s where a CRT pacemaker comes in.
What is a CRT pacemaker?
A CRT pacemaker, also known as cardiac resynchronization therapy, helps restore a more coordinated heartbeat. Traditional pacemakers typically have one or two leads that send electrical impulses to stimulate a slow or irregular heart to beat at a normal rate. A CRT pacemaker uses an additional lead to regulate both the left and right ventricles to ensure that they contract together.
How does it work?
The CRT pacemaker sends small electrical impulses to the ventricles that prompts them to beat in sync. When the heart is out of rhythm — called dyssynchrony — blood flow is disrupted. By resynchronizing the heart’s beating pattern, patients often experience better overall heart function, reduced symptoms, and an improved quality of life.
The additional lead that a CRT pacemaker uses is placed on the left ventricle to ensure that both the left and right ventricles contract at the same time. This coordinated effort improves the heart’s efficiency, which can be especially beneficial for heart failure patients who are struggling with symptoms like fatigue, shortness of breath, and fluid retention.
Who can benefit from a CRT pacemaker?
Patients with heart failure, especially those with weakened hearts or an uncoordinated heartbeat, are ideal candidates for CRT pacemakers. If medications or lifestyle changes aren’t enough to manage your symptoms, your cardiologist may recommend a CRT pacemaker to help improve your heart’s function and reduce symptoms.
CRT pacemakers are particularly effective for patients who have been diagnosed with dyssynchrony. This therapy can help restore the heart’s ability to pump blood efficiently and alleviate many of the symptoms associated with heart failure.
Key benefits of CRT pacemakers
- Improved blood flow – By syncing the heart’s rhythm, the blood flow becomes more efficient, which eases the burden on your heart.
- Symptom relief – Patients often report a reduction in symptoms like fatigue, shortness of breath, and swelling.
- Enhanced quality of life – With a better-functioning heart, you may experience more energy and increased stamina for daily activities.
