|
ablation |
removal or destruction |
|
|
angioplasty |
a procedure that reopens a narrowed vessel and restores blood flow. |
|
|
artificial pacemaker |
a battery-operated device that generates electrical impulses to regulate the heartbeat. It may be external or implanted, may be designed to respond to need, and may have the capacity to prevent tachycardia. |
|
|
cardiopulmonary resuscitation (CPR) |
Restoration of cardiac output and pulmonary ventilation after cardiac arrest using artificial respiration and chest compression or cardiac massage |
|
|
cardioversion |
correction of an abnormal cardiac rhythm. MAy be accomplished pharmacologically, with antiarrhythic drugs, or by application of electric current |
|
|
coronary angiography |
Radiographic study of the coronary arteries after introduction of an opaque dye by means of a catheter threaded through blood vessels into the heart |
|
|
coronary artery bypass graft (CABG) |
surgical creation of a shunt to bypass a blocked coronary artery. The aorta is connected to a point past the obstruction with another vessel or a piece of another vessel, usually the left internal mammary artery or part of the leg's saphenous vein |
|
|
coronary calcium scan |
method of visualizing vessel-narrowing calcium deposits in coronary arteries. |
|
|
creatine kinase MB |
enzyme released in increased amounts from cardiac muscle cells following myocardial infraction. |
|
|
CT angiography |
Computed tomography scan used to visualize vessels in the heart and other organs. Requires only a small amount of dye injected into the arm. Can rule out blocked coronary arteries that may cause a myocardial infraction in people with chest pain or abnormal stress tests |
|
|
defibrillation |
Use of n electronic device to stop fibrillation by delivering a brief electric shock to the heart. The shock may be delieverd to the surface of the chest, as by an automated external defibrillator, or directly into the heart through wire leads, using an implanted cardioverter defibrillator |
|
|
echocardiography |
a noninvasive method that uses ultrasound to visualize internal cardiac structure |
|
|
lipoprotein |
a compound of protein with lipid. Lipoproteins are classified according to density as very low-density (VLDL), low-density (LDL), and high-density(HDL). Relatively higher levels of HDL's have been correlated with cardiovascular health |
|
|
percutaneous transluminal coronary angioplasty (PTCA) |
Dilation of a sclerotic blood vessel by means of a balloon catheter inserted into the vessel and then inflated to flatten plaque against the arterial wall |
|
|
stent |
a small metal device in the shape of a coil or slotted tube that is placed inside an artery to keep the vessel open after balloon angioplasty |
|
|
stress test |
evaluation of physical fitness by continuous ECG monitoring during exercise. IN a thallium stress test, a radioactive isotope of thalium is administered to trace blood flow through the heart during exercise |
|
|
troponin (Tn) |
a protein in muscle cells that regulates contraction. Increased serum levels, primarily in the forms TnT and Tnl, indicate recent myocardial infraction |
