Cardiac Output
What is it? Why is it Vital? The amount of blood pumped out of the ventricle in a minute (most often refers to the blood
Cardiac Tamponade
Excess fluid between the parietal and pleural layers surrounding the heart restrict the contraction of the heart; early signs of cardiac tamponade may be a
Cardioversion
More accurately called synchronous cardioversion, an electrical current is applied to the heart when the ventricles are depolarizing (R wave as opposed to firing on
Catecholamines
