Term | Definition |
Aneurysm | Weakened spot of the artery wall that has streched or burst |
Anoxia | Absence of oxygen supply to cells that results in damage or death |
Anticoagulant | Drug that is used to prevent clot formation |
Antiplatelet | Drug that prevents accumulation of platelets |
Antithrombotic | Drug that inhibits clot formation by reducing the coagulation action of the blood protein thrombin |
Atherosclerosis | Accumulation of the fatty deposits in the walls of the arteries |
Atherothrombosis | Formation of a blood clot in an artery |
Atrial Fibrillation | Rapid and uncoordinated contractions |
Atrial flutter | Irregular heart beat in which contractions in atrium exceed the number of contractions in the ventricle |
Cholesterol | Dietary lipid normally synthesized by the body |
Depolarization | Process where the heart muscle conducts an electrical impulse causing a contraction |
Ectopic | Occurring in an abnormal location |
Electrical cardioversion | Process of applying an electrical shock to the heart with a defibrillator |

Hypoxia | Reduced oxygen deliver to cells |
Infarction | Area of tissue that has died because of a sudden lack of blood supply |
Ischemia | Deficient blood supply to an area of the body |
Ischemic stroke | Ischemia in the brain |
Lipoprotein | Protein found in the plasma that transports triglycerides and cholesterol |
Low-density lipoprotein | Bad Cholesterol |
Mitral valve stenosis | Disease of the mitral valve |
Platelets | Structures found in the blood that are involved in the coagulation process. |
Partial thromboplastin time | Test given to determine effectiveness of heparin in reducing antithrombotic activity |
Prothrombin time | Test given to determine the effectiveness of warfarin in reducing clotting time |
Refractory period | Time between contractiond that it takes for repolarization to occur |
Repolarization | Period of time when the heart is recharging and preparing for another contraction |
Rhabdomyolysis | Breakdown of muscle fibers and release muscle fiber contents into the circulation |
Stenosis | Stiffening and narrowing of artey walls |
Supraventricular Tachycardia | Heart rate up to 200 beats per minute that originates in an area above the ventricles |
