Q- What is Cardiac Resynchronization Therapy (CRT)?

Cardiac resynchronization therapy is a procedure to implant a device in your chest to make your's heart chambers contract in a more synchronized and efficient way. It uses a device called a bi-ventricular pacemaker that delivers electric signals to both the lower chambers of the heart so that both the ventricles contract at the same time thus maximizing the amount of blood that's pumped out of your heart. Sometimes along with a biventricular pacemaker, you may also need another device called Implantable Cardioverter Defibrillator (ICD) which helps to fix serious heart rhythm problems.
