Cardiac resynchronization therapy (CRT), also called biventricular pacing, uses an implantable biventricular pacemaker, about the size of a half dollar, which sends small electrical impulses to the heart to help the right and left ventricles pump together more normally.
To "resynchronize" contractions and improve the pumping efficiency of the heart, CRT uses three leads, one each going into the right atria, right ventricle and left ventricle. This pacemaker is usually implanted just below the collarbone.
This differs from a traditional pacemaker, which only treats the right ventricle.
Patients who use CRT usually enjoy improved life quality, improved ability to exercise and fewer hospitalizations for heart failure.
