There are two types of Cardiac resynchronization therapy devices. One device is a special kind of pacemaker. This is called a cardiac resynchronization therapy pacemaker (CRT-P) or biventricular pacemaker. Another device is called Cardiac resynchronization therapy with a pacemaker and an ICD but it also includes a built-in implantable cardioverter-defibrillator.
CRT therapy means you will need to have the pacemaker placed under the skin by minor surgery. Wires from the devices are connected to the ventricles on both sides of the heart. The CRT will send electrical signals to the ventricles for making them pump together.
Infection at the surgical site and/or reaction to the device material, inability to provide therapy when it is needed, or obtaining additional therapy when it is not needed are all risks associated with it.
In selected patients with heart failure (HF), reduced left ventricular (LV) function, and a broad QRS complex, randomised controlled trials (RCTs) have indicated that cardiac resynchronization therapy (CRT) prolongs survival and lowers morbidity.
The CRT device may be implanted as an outpatient procedure or as part of a hospital stay. Procedures may differ depending on your situation and the practices of the doctor. Discuss what will happen during the procedure with the doctor. The operation will take 3 to 5 hours.
