❏Echocardiography: use of sound waves to produce an
image on the heart
❏Electrocardiogram: record of the electrical currents of
the heart
❏Electrocardiography: procedure for recording the
electrical currents of the heart
❏Sonography: use of sound waves to produce diagnostic
images; ultrasound
❏Stress electrocardiogram: records electrical signals of
the heart while the patient experiences increases of
exercise stress
❏Transesophageal echocardiogram: record of the heart
using sound waves performed by inserting the
transducer into the esophagus
❏Vascular endoscopy: procedure to look inside a blood
vessel
❏Venogram: record of a vein
❏Professional terms
❏Blood pressure: the force exerted by blood on the walls
of blood vessels
❏Diastolic pressure: pressure exerted on blood vessels
when the heart is relaxed
❏Systolic pressure: pressure exerted on blood vessels
when heart is contracting
❏Cardiologist: heart specialist
❏Cardiology: branch of medicine dealing with the heart
❏Cardiovascular: pertaining to the heart and blood
vessels
❏Circulation: moving of blood from the heart through the
vessels and back to the heart
❏Coronary circulation: circulation of blood from the heart
to the heart muscle
❏Pulmonary circulation: circulation of blood from the
heart to the lungs
❏Systemic circulation: circulation of blood from the heart
to the rest of the body
❏Phlebologist: specialist in veins
❏Phlebology: study of veins
❏Phlebotomist: one who draws blood
❏Phlebotomy: incision into a vein- drawing blood
❏9.4 Diagnosis and Pathology
❏Heart:
❏Angiocarditis: inflammation of the heart vessels
❏Atrial fibrillation: quivering or spontaneous contraction
of muscle fibers in the heart’s atrium
❏Atrial septal defect: flaw in the septum that divides the
two atria of the heart
❏Cardiac arrest: cessation of functional circulation
❏Cardiomyopathy: disease of the heart muscle
❏Congestive cardiomyopathy: heart cavity is unable to
pump all the blood out of itself and becomes stretch,
which causes weak/slow pumping of blood
❏Dilated cardiomyopathy: another term for congestive
cardiomyopathy
❏Hypertrophic cardiomyopathy: heart muscle becomes
enlarged and blocks blood flow
❏Restrictive cardiomyopathy: heart muscle hardens,
restricting the expansion of the heart, thus limiting the
amount of blood it can pump to the rest of the body
❏Carditis: inflammation of the heart
❏Congenital heart defect: flaw in the structure of the heart
present at birth
❏Congestive heart failure: heart failure characterized by
the heart cavity being unable to pump all the blood out
of itself
❏Coronary thrombosis: obstruction of a coronary artery
by a clot
❏Endocarditis: inflammation of the tissue lining the inside
of the heart
❏Myocardial infarction: death of heart muscle tissue
❏Myocardial ischemia: blockage of blood to the heart
muscle
❏Myocarditis: inflammation of the heart muscle
❏Pericardial effusion: fluid pouring out into the tissue
around the heart
❏Pericarditis: inflammation of the tissue around the heart
❏Valvulitis: inflammation of the heart valve
