A

the angle between the sternum body and manubrium

Also called the Angle of Louis

120

A

the load, or resistance, against which the left ventricle must eject its volume of blood during contraction. The resistance is produced by the volume of blood already in the vascular system and by the constriction of the vessel walls

121
Q

Aneurysm

A

a sac formed by localized dilatation of the wall of an artery, a vein, or the heart

122
Q

Atrioventricular Node

A

an area of specialized cardiac muscle that receives the cardiac impulse from the sinoatrial (SA) node and conducts it to the bundle of His and thence to the Purkinje fibers and walls of the ventricles. The AV node is located in the septal wall between the left and right atria.

123
Q

Claudication

A

Cramping or pain in a leg caused by poor blood circulation. This condition is frequently caused by hardening of the arteries (atherosclerosis). Intermittent claudication occurs only at certain times, usually after exercise, and is relieved by rest

124

125
Q

Gangrene

A

the death of body tissue, generally in considerable mass, usually associated with loss of vascular (nutritive) supply, and followed by bacterial invasion and putrefaction. Although it usually affects the extremities, gangrene sometimes may involve the internal organs. Signs depend on the site and include fever, pain, darkening of the skin, and an unpleasant odor. If the condition involves an internal organ, it is generally attended by pain and collapse

126
Q

Jugular venous pressure

A

blood pressure in the jugular vein, which reflects the volume and pressure of venous blood. JVP is estimated by positioning the head of a supine patient at a 30- to 45-degree angle and observing the neck veins. If the neck veins are filled only to a point a few millimeters above the clavicle at the end of exhalation, JVP is usually normal. With an elevated JVP the neck veins may be distended as high as the angle of the jaw. An elevated JVP is typically a sign of congestive heart failure.

127

A

a disorder characterized by sudden attacks of respiratory distress that awaken the person, usually after several hours of sleep in a reclining position. This occurs because of increased fluid central circulation with reclining position. It is most commonly caused by pulmonary edema resulting from congestive heart failure. The attacks are often accompanied by coughing, a feeling of suffocation, cold sweat, and tachycardia with a gallop rhythm. Sleeping with the head propped up on pillows may prevent PND, but treatment of the underlying cause is required to prevent fluid from accumulating in the lungs

128

136
Q

Brawny edema

A

change typical of chronic venous insufficiency, characterized by thickening, induration, liposclerosis and non-pitting edema; the brawny color is due to hemosiderin from lysed RBCs; with chronic ischemia, the skin undergoes atrophy, necrosis, and stasis ulceration, surrounded by a rim of dry, scaling, and pruritic skin

137
Q

Coarctation

A

narrowing. (coarctation of aorta a local malformation marked by deformed aortic media, causing narrowing of the lumen of the vessel.)

138
Q

Embolism

A

the sudden blocking of an artery by a clot of foreign material (Embolus) that has been brought to its site of lodgment by the blood current. The obstructing material is most often a blood clot, but it may be a fat globule, air bubble, piece of tissue, or clump of bacteria.

139
Q

141
Q

Patent ductus arteriosus

A

• A condition in which the normal channel between the pulmonary artery and the aorta fails to close at birth. In fetal circulation, the blood bypasses the pulmonary circuit because oxygen and carbon dioxide are exchanged through the placenta. After birth, this channel normally closes in response to expansion of the lungs. With this, blood pools back into the lungs, causing the heart to work harder than necessary.
