A more accurate way to determine rate is to count the number of large boxes between QRS complexes for the ventricular rate (or the number of large boxes between P waves for the atrial rate) and divide 300 by this number. This method is es ...

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.
