- S -

• S tach

Sinus tachycardia.



• SA node

Sinoatrial node.



• Sarcoidosis

A systemic disease of unknown causes. It is characterized by widespread formation of lesions, known as granulomas, in the lungs, liver, spleen, skin, eyes, parotid glands, and the lymph nodes of the mediastinum. It is often associated with a depression of cellular immunity. It is most prevalent in the southern United States. Sarcoidosis is not treatable by surgery, but surgery may be performed to make the diagnosis and to differentiate the sarcoid lesions from other causes such as tuberculosis or fungal infections.



• Sarcoidosis Cordis

A form of sarcoidosis in which lesions develop in the myocardium, resulting in cardiac failure in severe cases.



• SBP

Systolic blood pressure.



• Sed. rate

Erythrocyte sedimentation rate.



• SEM

Systolic ejection murmur.



• SGOT

Serum glutamic oxaloacetic transaminase (ast).



• SGPT

Serum glutamic pyruvic transaminase.



• Shock

Acute peripheral circulatory failure due to derangement of circulatory control or loss of circulating fluid, marked by hypotension, coldness of skin, usually tachycardia, and often anxiety; decreased cardiac output;.



• Sinus node

Bundle of excitatory tissue found in the right atrium that functions as the pacemaker of the heart.



• Sinus of Valsalva

The portion of the aortic root just distal to the aortic valve containing the coronary ostia.



• SO2

Percent saturation of hemoglobin with oxygen, in the arterial blood - sao2, in the venous blood - svo2.



• Solubility

The ability of a gas to dissolve into plasma and rbc water.



• Sphygmomanometer

An instrument used to measure blood pressure.



• Starch

A complex carbohydrate that is stored in plants and used for food.



• Stenosis

A narrowing or blockage of a coronary artery.



• Stent

A device used to treat narrowing or blockage of the coronary arteries. Performed in the cardiac catherization laboratory, the stent is place by the cardiologist using x-ray guidance.



• Sternotomy

A type of incision in the center of the chest that allows access to the heart.



• Stethoscope

An instrument used to listen to heart sounds.



• STICU

Surgical trauma intensive care unit.



• Stricture

An abnormal narrowing of a tubular organ or body part. Strictures can occur as a result of injury, scarring, inflammation, or other disease processes. Examples of strictures are strictures of arteries, strictures of the esophagus, strictures of the airway passages, or strictures of the intestines. Depending on the location and the cause of the stricture, surgery may be performed.



• Sublingual

Beneath the tongue.



• Supraventricular arrhythmia

An irregular heart beat that originates in the atria or av node.



• Survival Rates

Survival rates indicate how many patients or grafts (transplanted organs) are alive/functioning at a set time posttransplant. Survival rates are often given at one, three and five years. Policy modifications are never made without examining their impact on transplant survival rates. Survival rates improve with technological and scientific advances. Developing policies that reflect and respond to these advances in transplantation will also improve survival rates.



• SV

Stroke volume.



• SV tach

Supraventricular tachycardia.



• SVCSVC

Superior vena cava.



• SVG

Saphenous vein graft.



• SVO2

Mixed venous oxygen saturation.



• SVR

Systemic vascular resistance ([map-cvp]/co).



• Systemic Circulation

Circulation of blood throughout the entire body.



• Systole

Referring to the period of time during contraction of the ventricle(s).
