Mediastinum
Where heart is located behind sternum on left side of chest
Inner layer, lines heart chambers, smooth, thin layer that reduces friction as the blood passes through heart chambers
Endocardium
Middle layer, thick muscle, contraction of this layer develops the pressure required to pump blood through blood vessels
Myocardium
Outer layer, forms the visceral layer of pericardial sac, fluid between layers of pericardial sac reduces friction as heart beats
Epicardium
Atrioventricular valve, between right atrium and ventricle, has 3 leaflets or cusps
Tricuspid valve
A semilunar valve, between right ventricle and pulmonary artery
Pulmonary valve
An atrioventricular valve, between left atrium and ventricle, bicuspid valve
Mitral valve
Semilunar, between left ventricle and aorta
Aortic valve
Relaxation phase of a heart beat
Diastole
Contraction phase of heartbeat
Systole
Where electrical pulse begins, causes wave of electricity to travel through atria and contract (systole)
Sinoatrial (SA) nods
Second wave of electricity that is stimulated
Atrioventricular (AV) node
Third wave of electricity
Bundle of his
Electrical wave travels down bundle branches within inter ventricular septum
4th wave of electricity
Last step of electrical stimulation, in ventricular myocardium, results in ventricular systole
Purkinje fibers
Precedes atrial systole
P wave
Precedes ventricular systole
QRS complex
Precedes ventricular diastole
T wave
Coronary artery supplies
Myocardium
During ventricular systole
Blood is under great pressure, top number of blood reading
During ventricular diastole
Blood isn’t being pushed from heart at all, blood pressure drops to lowest point
Record of a vessel
Angiogram
Inflammation of a vessel
Angiitis
Surgical repair of vessel
Angioplasty
Ruptured artery
Arteriorrhexis
Surgical removal of fatty substance
Atherectomy
Fatty substance tumor/ growth
Atheroma
State of slow heart rate
Bradycardia
Enlarged heart
Cardiomegaly
Ruptured heart
Cardiorrhexis
Inflammation of a vein
Phlebitis
Surgical repair of a valve
Valvoplasty
Listening to sounds within body using a stethoscope
Auscultation
Area of necrotic tissue due to loss of blood supply
Infarct
Local and temporary deficiency of blood supply due to a circulatory obstruction
Ischemia
Abnormal heart sound such as soft blowing sound or a harsh click
Murmur
To flow backwards
Regurgitation
Electrical impulse is blocked from traveling down bundle branches; results in ventricles beating at different rate than atria
Bundle branch block (BBB)
Myocardial disease, may be caused by viral infection, congestive heart failure, or alcoholism
Cardiomyopathy
Left ventricle muscle is too weak to efficiently pump blood, results in weakness, breathlessness, and edema
Congestive heart failure (CHF)
Inflammation of lining membranes of heart; if cause is bacterial may have a bacterial colony form, called vegetation
Endocarditis
Extremely serious arrhythmia characterized by quivering of heart fibers, cardiac arrest and death can occur
Fibrillation
Arrhythmia in which atria beat to rapidly, but in a regular pattern
Flutter
Cusps are too loose and fail to shut tightly, allowing regurgitation
Heart valve prolapse
Cusps are too stiff, unable to shut tightly, allowing regurgitation
Heart valve stenosis
Occlusion of coronary artery; heart attack
Myocardial infarction (MI)
Weakness and ballooning of arterial wall; commonly seen in abdominal and cerebral arteries
Aneurysm
Hardening and loss of elasticity of arterial walls, often due to atherosclerosis
Arteriosclerosis
Liquid plaques form in arterial wall
Atherosclerosis
Obstruction of blood vessel by blood clot that has broken off from a thrombus in another site
Embolus
High blood pressure
Hypertension (HTN)
Low blood pressure
Hypotension
Congenital heart anomaly where fetal connection between pulmonary artery and aorta fails to close at birth
Patent ductus arteriosus (PDA)
Blood clot within a blood vessel, may partially or completely occlude blood vessel
Thrombus
Blood test measures amount of cholesterol and triglycerides in blood; indicator of atherosclerosis risk
Serum lipoprotein level
Xrays taken after injection of opaque dye into blood vessel
Angiography
Nuclear scan using radioactive thallium, especially useful in determining myocardial damage
Cardiac scan
Using ultrasound to watch blood flow through vessels to see velocity, indicates clots or thromboses
Doppler ultrasonography
Use of ultrasound to visualize internal cardia structures especially valves
Echocardiography
Xray of veins, identify thrombus
Venography
Balloon catheter is inserted through skin into coronary artery; inflated to dilate the narrow blood vessel
Percutaneous transluminal coronary angioplasty (PTCA)
Produce vasodilation to decrease blood pressure
ACE inhibitor drugs, lotensin, capoten
Reduces or prevents cardiac arrhythmias
Tambocor, corvert
Prevents blood clot formation
Anticoagulant, warfarin, Coumadin
Reduces blood cholesterol level
Antilipidemic, cholestyramine
Decreases force of heart beat to treat hypertension, angina, or CHF
Calcium channel blocker, cardizem, procardia
Contracts smooth muscle in wall of blood vessel to raise blood pressure
Vasoconstrictor, aramine
Relaxes smooth muscle in wall of vessel to reduce blood pressure and increase blood flow to ischemic area
Vasodilator, nitro-dur, vasodilan
