Question

How is the heart restarted after bypass surgery?

Answer 1

As soon as the procedure is completed, the surgeon restores blood flow to the heart, and which may restart on its own. This is due to the solution used to stop the heart from being washed out by the blood.

Complete answer:
Usually the heart restarts on its own, or sometimes with a small electrical shock. This is the most widely performed kind of heart surgery, also known as coronary artery bypass graft surgery (CABG), or coronary artery bypass (CAB), coronary bypass, or bypass surgery.
This surgery involves using a healthy section of blood vessel from another part of the body to bypass a part of a diseased or blocked coronary artery. This ensures a new route for blood to flow, so that the heart muscle will get the oxygen-rich blood it needs to work properly.
During the bypass surgery, the breastbone (i.e. sternum) is divided, and then the heart is stopped, and the blood is sent through a heart-lung machine. Unlike the any other kinds of heart surgery, the chambers of the heart are not opened during the bypass surgery.
If a person is on the heart-lung bypass machine, the doctor will restart your heart. After that the bypass grafts have been sewn in place with strong stitches (sutures), the doctor will take the clamp off of the person's aorta which will allow blood to flow to your heart, thus the heart will typically start to beat again.

Note: When the heart starts to beat again, the patient will be taken off the heart-lung bypass machine. Sometimes the surgeon may then apply a small electric shock, or the anesthesiologist may administer another medicine in order to help your heart muscle regain its natural rhythm.
