| Angina | Intermittent chest pain,usually of short duration. |
| Angiorrhaphy | Suturing of a blood vessel. |
| Aneurysm | A localized,abnormal dilation of a blood vessel,usually an artery,thinning of a blood vessel wall. |
| Aorta | Largest artery in the body which collects blood from from the left ventricle, and delivers it to all parts of the body via smaller arteries. |
| Arrhythmia | Irregularity in the heart action/beat. |
| Artery | Vessel that carries blood from the heart to body tissues and organs. (oxygenated) |
| Arteriole | A small artery. |
| Arteriosclerosis | Abnormal condition of hardening of the arteries. |
| Atherosclerosis | Abnormal condition in which there is a build up of fatty deposits in the arteries. |
| Bicuspid Valve | A valve with two cusps,through which blood passes from the left atrium to the left ventricle. (mitral valve) |
| Blood Pressure | The force exerted by the blood against the arterial walls during the contraction phase and relaxation phase of the heart. |
| Bradycardia | Slow heart beat. |
| Bruit | A soft blowing sound heard on auscultation. (murmur) |
| Bundle of His | Specialized muscle fibres in the wall between the ventricles that carry the electric impulses to the ventricles. |
| Capillaries | Microscpoic blood vessels connecting arterioles and venules. |
| Cardiac Catheterization | Test which helps to assess the heart,major coronary vessels,valves and septum. Involves a catheter being inserted into the right side of the heart through an arm or leg. |
| Cardiomegaly | Enlargement of the heart. |
| Cardiomyopathy | Any disease of the heart muscle that diminishes cardiac function (caused by viral infections and metabolic disorders). |
| Cardiovascular System | System composed of the heart,blood vessels and their function within the body. |
| Cardioversion | Conversion of a cardiac arrhythmia to normal sinus rhythm by the use of a device called a defibrillator. Applying controlled electrical shock to the exterior of the chest. |
| Carditis | Inflammation of the heart. |
| CCU | Coronary Care Unit. |
| Conductive Tissue | Highly specialized cardiac tissue which initiates and continues contraction impluses. |
| Congenital Septal Defect | Small hole(s) within the atrial or ventricular septums,which is present at birth. |
| Congestive Heart Failure(CHF) | Failure of the heart to pump an adequate amount of blood to the tissues and organs. |
| Coronary Artery Disease (CAD) | Any disease which alters the ability of the coronary artery to deliver the amount of blood that is required by the heart muscle. |
| Diaphoresis | Profuse sweating. |
| Diastole | The relaxation phase of the heart. |
| Dyspnea | Difficult breathing. |
| Echocardiography | Examination which uses ultrasound to provide assessment of the structures and function of the heart. |
| Electrocardiogram | A graphic record of the electrical impulses generated by the conduction system of the heart. |
| Embolus | A thrombus which has broken loose from the vein wall and begun to travel through the vascular system. |
| Endocardium | Innermost layer of the heart. |
| Epicardium | Outermost layer of the heart. |
| Fibrillation | Quivering or spontaneous muscle contractions, causing ineffectual cardiac contractions. |
| Heart | A hollow, muscular organ that pumps blood through the arteries, cappillaries, and veins. |
| Holter Monitor | A small, portable ECG monitor that assesses heart and pulse action as the patient engages in daily activities. 24-48 hr of ECG/EKG Tracing. |
| Hypertension | Elevated (high) blood pressure. |
| Infarct | Area of tissue that undergoes necrosis after cessation of blood supply. |
| Inferior Vena Cava | Large vein which collects and carries deoxygenated blood from the lower portion of the body and enters the right atrium. |
| Insufficiency | Inability of valves to close properly. |
| Ischemia | Lack of oxygen or blood to body tissues. Local and temperary deficiency of blood supply. |
| Left Atrium | Chamber which receives oxygenated blood from the lungs. |
| Left Ventricle | Chamber which pumps oxygenated blood to the body via the aorta. |
| Ligated | Tied. |
| Myocardial Infarction | Life threatening condition characterized by necrosis in the myocardium due to lack of oxygen. Circulator blockage. |
| Myocardium | Musclar layer of the heart. |
| Necrosis | Destruction (death) of tissue. |
| Pacemaker | An electrical device that controls the beating of the heart by rhythmic series of electrical dischages. |
| Pallor | Paleness. |
| Pericardium | Fibrous sac which encloses the heart. |
| Phlebitis | Inflammation of a vein. |
| Pulmonary Artery | Carries deoxygenated blood from the right ventricle to the lungs. |
| Pulmonary Vein | Carries oxygenated blood back to the heart from the lungs. |
| Pulmonary Semilunar Valve | Prevents the backflow of blood into the right ventricle. |
| Purkinje Fibers | Extend up the walls of the ventricles and transmit electrical impluses to both ventricles, causing them to contract. |
| Right Atrium | Chamber which collects deoxygenated blood from the body. |
| Right Ventricle | Chamber which pumps deoxygenated blood from the heart to the lungs. |
| Septum | Muscular wall which divides the right and left sides of the heart. |
| Shunt | A passage between two blood vessels or between two sides of the heart. |
| Sphygmomanometer | Instrument for measuring blood pressure. |
| Stenosis | Narrowing. |
| Stress/Exercise Testing | Measures the efficiency of the heart during a period when it is subjected to predetermined exercises (treadmill or bicycle). |
| Stripped | Removed. |
| Superior Vena Cava | Large vein which collects and carries deoxygenated blood from the top portion of the body and enters the right atrium. |
| Systole | The contract phase of the heart. |
| Tachycardia | Rapid heart action. |
| Thromophlebitis | Inflammation of a vein wall, which may cause clots to form. |
| Thrombosis | Abnormal condition of a blood clot in the blood vessel. |
| Thrombus | A blood clot that obstructes a vessel. Becomes embolus if moves from location. |
| Tricuspid Valve | A valve with three cusps, located between the right atrium and right ventricle, which allows blood to pass into the right ventricle. |
