Q

Atria

A

two upper chambers of the heart, left and right atria, which receive blood and perform 30% of the work

both atria contract at same time, but pump blood into different areas.

Right ATRIUM pumps blood downward through tricuspid valve into right ventricle.

Left ATRIUM receives blood from pulmonary veins, when it contracts it forces blood downward through mitral valve into left ventricle

Pulse Oximeter

A

device used to monitor heart rate and measure the saturation of peripheral oxygen (SpO2) in the blood

differentiates between oxygenated and deoxygenated blood by passing two beams of light, infrared and red, through the finger to a light detector

Bright red oxygenated blood absorbs more infrared light

dark red deoxygenated hemoglobin absorbs more red light

Normal SpO2 for healthy individuals is 96% to 99%

travels under much less pressure than arterial blood

contain one way valves that facilitate circulation by preventing the backflow of blood

pumping action created by contraction and relaxation of leg muscles also helps propel blood upward

type of vascular disease associated with tobacco use, marked by inflammation and clot formation within small vessels of the hands and feet, which may lead to gangrene and surgical amputation; sometimes called Buerger’s disease

158
Q

varicose veins

A

bulging, distended veins due to incompetent valves, most commonly in the legs

159
Q

Angiography

A

Diagnostic or therapeutic radiography (radiological imaging) of the heart and blood vessels

160
Q

Automated external defibrillator (AED)

A

Small computer-driven defibrillator that analyzes the patient’s rhythm, selects the appropriate energy level, charges the machine, and delivers a shock to the patient

161
Q

Automatic implanted cardioverter defibrillator (AICD)

A

Very small defibrillator, surgically implanted in patients with a high risk for sudden cardiac death, that automatically detects and treats life-threatening arrhythmias

162
Q

Cardiac catheterization

A

Evaluation of the heart vessels and valves via the injection of dye that shows up under radiology

163
Q

Cardiopulmonary resuscitation (CPR)

A

Emergency procedure that provides manual external cardiac compression and sometimes artificial respiration

164
Q

Cardioversion

A

Restoration of normal sinus rhythm (NSR) by chemical or electrical means

165
Q

Coronary artery bypass graft (CABG)

A

Surgical creation of an alternate route for blood flow around an area of coronary arterial obstruction

166
Q

Defibrillation

A

Delivery of an electric shock with the goal of ending ventricular fibrillation and restoring NSR

167
Q

Electrocardiography (ECG, EKG)

A

Creation and study of graphic records (electrocardiograms) of electric currents originating in the heart

168
Q

Event recorder

A

Portable monitoring device that transmits heart rhythms by telephone to a central laboratory, where dysrhythmias can be detected and analyzed

169
Q

Holter monitor

A

Portable device worn by a patient during normal activity that records heart rhythm for up to 24 hours

170
Q

International normalized ratio (INR)

A

Standardized method of checking the prothrombin time (PT); used to monitor and adjust warfarin (Coumadin) dosage in order to maintain a balance between clot prevention and excessive bleeding

171
Q

pacemaker

A

Device that can trigger the mechanical contractions of the heart by emitting periodic electrical discharges

172
Q

Partial thromboplastin time (PTT)

A

Measure of blood-clotting time, used to monitor heparin therapy; heparin is an anticoagulant medication that slows the clotting time of blood. A balance must be maintained between clot prevention and excessive bleeding.

173
Q

Percutaneous transluminal coronary angioplasty (PTCA)

A

Method of treating a narrowed coronary artery via inflation and deflation of a balloon on a double-lumen catheter inserted through the right femoral artery

174
Q

Prothrombin time (PT)

A

Procedure that measures the clotting time of blood; used with the international normalized ratio (INR) to assess levels of anticoagulation in patients taking warfarin (Coumadin). A balance must be maintained between clot prevention and excessive bleeding.

175
Q

stress test

A

Treadmill test that can show if the blood supply is reduced in the arteries that supply the heart

176
Q

Transesophageal echocardiography (TEE)

A

Study of the heart via a probe placed in the esophagus

177
Q

Troponin

A

Protein released into the body by damaged heart muscle, considered the most accurate blood test to confirm the diagnosis of an MI
