Cardiac Resynchronization

CRT is used to treat the symptoms and complications associated with certain types of heart failure. It helps the pumping chambers to beat in a coordinated manner so that the heart works properly. By improving blood flow, CRT may reduce heart failure symptoms, improving patients’ quality of life and reducing mortality.

Cardiac resynchronization therapy (CRT) is treatment to help your heart beat with the right rhythm. It uses a pacemaker to restore the normal timing pattern of the heartbeat.

The CRT pacemaker coordinates how timing of the upper heart chambers (atria) and the lower heart chambers (ventricles). It also works on the timing between the left and right sides of the heart.

When your heart doesn’t pump strongly enough, fluid can build up in your lungs and your legs. This is called heart failure. This condition can happen when the two bottom chambers (ventricles) of your heart don’t beat at the same time.

Doctors at ASC of The Heart Institute may find out that you also need an implantable cardioverter defibrillator (ICD). This device helps fix serious heart rhythm problems. If you need this device, it may be combined with the CRT.

CRT therapy means you will need to have the pacemaker placed under your skin by minor surgery. Wires from the device are connected to the ventricles on both sides of your heart. The CRT device sends electrical signals to the ventricles to make them pump together the way they should.
