A

Electrocardiogram (ECG)

99
Q

extra heartbeats that start in the upper chambers of your heart. When the premature, or early, signal tells the heart to contract, there may not be much blood in the heart at that moment. That means there’s not much blood to pump out

A

Premature atrial contraction (PAC)

100
Q

extra heartbeats that begin in one of the heart’s two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a sensation of a fluttering or a skipped beat in the chest.

A

Premature ventricular contraction (PVC)

101
Q

a type of irregular heart rhythm (arrhythmia). The lower heart chambers contract in a very rapid and uncoordinated manner. As a result, the heart doesn’t pump blood to the rest of the body.

A

Ventricular fibrillation

102
Q

a type of abnormal heart rhythm, or arrhythmia. It occurs when the lower chamber of the heart beats too fast to pump well and the body doesn’t receive enough oxygenated blood.

A

Ventricular Tachycardia (VT)

103
Q

A

Cardiac tamponade

108
Q

Any disorder that affects the heart muscle; causes the heart to lose its ability to pump blood well. In some cases, the heart rhythm also becomes disturbed.

A

Cardiomyopathy

109
Q

when the heart chambers enlarge and lose their ability to contract. It often starts in the left ventricle (bottom chamber). As the disease gets worse, it may spread to the right ventricle and to the atria (top chambers).

A

Dilated cardiomyopathy (DCM)

110
Q

a procedure used to obtain myocardial tissue to monitor for the occurrence of allograft rejection after cardiac transplantation or, less commonly, diagnose diseases of the myocardium

A

Endomyocardial biopsy (EMB)

111
Q

a condition affecting the left ventricle, the main pumping chamber of the heart. The walls of the left ventricle become thick and stiff. Over time, the heart can’t take in or pump out enough blood during each heartbeat to supply the body’s needs.

A

Hypertrophic cardiomyopathy (HCM)

112
Q

an inflammation of the heart caused by a bacterial or fungal infection of the heart valves or the inner lining of the heart (endocardium). If it is not treated quickly, it can lead to life-threatening complications.

A

Infective endocarditis (IE)

113

A

Janeway’s lesions

114
Q

the valve’s flaps do not always fit and close properly between each beat of the heart, which may cause the valve to leak blood backward through the valve back to the left atrium. This condition is called mitral valve regurgitation.

A

Mitral valve prolapse (MVP)

115
Q

involve inflammation of the heart in response to an infection or some other trigger. Symptoms can include shortness of breath, chest pain, or the feeling of a rapid or abnormal heart rhythm.

Dissection (tearing of the inner layer of the vessel) results from the creation of a false lumen (between the intima and the media) through which blood flows.

A

Aortic dissection

127
Q

common disorder in women and older persons. Condition in which leg veins and valves fail to keep blood moving forward. Results in ambulatory venous hypertension.

A

Chronic venous insufficiency (CVI)

128
Q

chronic ischemic rest pain lasting more than 2 weeks, arterial leg ulcers, or gangrene of the leg as result of PAD.

A

Critical limb ischemia

129
Q

thrombus deep in the vein, most commonly by the iliac and femoral veins.

A

Deep vein thrombosis (DVT)

130
Q

blood clot that forms in a blood vessel, breaks off, and travels to another are of the body in the blood.

A

Embolus

131
Q

ischemic muscle ache or “leg attack” that is precipitated by exercise, resolves with rest, and is reproducible.

A

Intermittent claudication

132
Q

condition that involves thickening of the artery walls, which results in progressive narrowing of the arteries of the upper and lower extremities.

A

Peripheral artery disease (PAD)

133
Q

occurs in 20%-50% of patients with VTE. venous stress disorder that develops from-long term effects from a previous DVT.

A

Post-thrombotic syndrome

134
Q

overarching term that encompasses raynaud’s disease and syndrome.

A

Raynaud’s phenomenon

135
Q

formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein.

A

Superficial vein thrombosis (SVT)

136
Q

nonathersclerotic, segmental, recurrent inflammatory disorder of the small and medium-sized arteries and veins of the upper and lower extremities

A

Thromboangiitis obliterates (TAO)

137
Q

blood clot that forms inside on of your veins or arteries

A

Thrombus

138
Q

dilated tortuous subcutaneous veins most commonly found in the saphenous vein system. May be small and innocuous or large and bulging.

A

Varicose veins

139
Q

also known as venous thrombosis, a condition in which a thrombus forms in association with inflammation of the vein. Most common disorder of the veins.

A

Venous thromboembolism (VTE)

140
Q

three factors that cause venous thrombosis
1. Venous stasis
2. Damage of the endothelium
3. Hypercoagulability of the blood.

A

Virchow’s triad

141
Q

acute life threatening hypersensitivity (allergic) reaction to a sensitizing substance. Immediate reaction causes massive vasodilation, release of vasoactive mediators, and an increase in capillary permeability.

A

Anaphylactic shock

142
Q

occurs when either systolic or diastolic dysfunction of the hearts pumping occurs, resulting in reduced stroke volume (SV), cardiac output (CO) and BP.

A

Cardiogenic shock

143
Q

occurs from the inadequate fluid volume in the intravascular space to support adequate perfusion.

A

Hypovolemic shock

144
Q

failure of two or more organ systems in an acutely ill patient such that homeostasis cannot be maintained without intervention.

A

Multiple organ dysfunction syndrome (MODS)

145
Q

develops when a physical obstruction to blood flow occurs, resulting in decreased CO.

A

Obstructive shock

146
Q

hemodynamic phenomenon that can occur within 30 minutes of a spinal cord injury at the 5th thoracic (T5) vertebra or above and lasts up to 6 weeks.

A

Neurogenic shock

147
Q

life threatening syndrome that arises when the body’s response to infection injures its own tissues and organs.

A

Sepsis

148
Q

subset of sepsis and is characterized by persistent hypotension, despite adequate fluid resuscitation, and inadequate tissue perfusion resulting in tissue hypoxia.

A

Septic shock

149
Q

decreased tissue perfusion and impaired cellular metabolism. This results in an imbalance between the supply of and the demand for oxygen and nutrients.

A

Shock
