Cardiac resynchronization therapy (CRT) is a treatment for heart conditions where the heart's pumping is uneven due to electrical conduction issues, such as left bundle branch block. CRT devices are implanted to synchronize the heart's ventricles, improving cardiac output and patient quality of life. The device uses leads to bypass blockages and restore synchronized heart function.
