So, from what you know so far, if the AV node does not receive any signals from the SA node or atria, it can’t work and therefore, logically, the patient’s heart should stop.

Cardiac surgery



Cardiovascular (heart) surgery is surgery on the heart or great vessels performed by cardiac surgeons. Frequently, it is done to treat complications of ischemic heart disease (for example, coronary artery bypass grafting), correct congenital heart disease, or treat valvular heart disease from various causes including endocarditis, rheumatic heart disease and atherosclerosis. It also includes heart transplantation.
