Cardiac resynchronization therapy (CRT)

UI heart researchers are evaluating new methods for placing implantable cardiac resynchronization devices in heart failure patients.

What is a CRT device?

CRT devices such as biventricular pacemakers, use electrical stimulation to synchronize and strengthen the heartbeat and improve the flow of blood from the heart.

What does a CRT device do?

These devices also function as defibrillators, capable of sending an electrical shock to the heart to stop dangerously rapid rhythms.
