Things About Heart Pacemaker Surgery You Need To Know
Heart pacemaker surgery is a procedure to implant a device that helps control abnormal heart rhythms. This type of surgery is also called cardiac resynchronization therapy (CRT) or biventricular pacing. The heart has four chambers: the two atria (upper chambers) and the two ventricles (lower chambers). The atria receive blood from the body and pump it into the ventricles. The ventricles then pump blood to the lungs and the rest of the body. In people with heart pacemaker surgery, the atria and ventricles don't always work together. This is called heart block. Heart block can cause the heart to beat too slowly. A pacemaker is a small device that's placed under the skin in the chest. It uses electrical pulses to help control the heart rate. Heart pacemaker surgery is done to treat heart block and other conditions that cause the heart to beat abnormally. The surgery is usually done when other treatments, such as medication, have failed.
