heart block
disease of the electrical system of he heart which controls activity of heart muscle
first-degree (heart block)
atrioventricular (AV) block in which atrial electrical impulses are delayed by a fraction of a second before being conducted to the ventricles
second-degree (heart block)
AV block in which only some atrial electrical impulses are conducted to the ventricles
third-degree (heart block)
AV block in which no electrical impulses reach the ventricles; also called complete heart block (CHB)
heart failure (HF)
occurs when the heart is unable to pump enough blood flow to meet the needs of the body and can cause a number of symptoms, such as shortness of breath, leg swelling, and exercise intolerance
hypertension (HTN)
consistently elevated blood pressure, causing damage to the blood vessels and, ultimately, to the heart
hyper
excessive, above normal
-tension
to stretch

isch

-emia

mitral value prolapse (MVP)
Structural abnormality in which the mitral (bicuspid) valve doesn’t close completely, resulting in a back flow of blood into the left atrium with each contraction
Murmur
abnormal sound heart on auscultation caused by defects int he valves or chambers of the heart
myocardial infarction (MI)
necrosis of a portion of cardiac muscle caused by partial or complete occlusion of one or more coronary arteries; also called heart attack
my/o
muscle
-al
pertaining to
patent ductus arteriosus (PDA)
Failure of the ductus arteriosus (which connects the pulmonary artery to the aortic arch in a fetus) to close after birth, resulting in an abnormal opening between the pulmonary artery and the aorta
Raynaud disease
Severe, sudden vasoconstriction and spasm in fingers and toes followed by cyanosis after exposure to cold temperature or emotional stress; also called Raynaud phenomenon
rheumatic heart disease
Streptococcal infection that causes damage to the heart valves and heart muscle, most commonly in children and young adults
Stroke
Damage to part of the brain as a result of interruption of its blood supply caused by bleeding within brain tissue or, more commonly, blockage of an artery; also called cerebrovascular accident (CVA)
Thromus
a stationary blood clot formed within a blood vessel or within the heart, commonly causing vascular obstruction; also called blood clot
thromb
blood clot
-us
condition, structure
deep vein thrombosis (DVT)
formation of a blood clot in a deep vein of the body, occurring most commonly in the lower legs
transient ischemic attack (TIA)
blood supply to part of the brain is briefly interrupted but doesn’t cause permanent brain damage and may be a warning sign of a more serious and debilitating stroke int he future; also called ministroke
Cardiac catheterization
insertion of a small tube (catheter) through a large vein or artery, usually of an arm (brachial approach) or leg (femoral approach), which is threaded through a blood vessel until it reaches the heart: used to inject a contrast medium for imagining, diagnosing abnormalities, obtaining blood samples, or measuring pressure within the heart, and often includes interventional procedures such as anioplasty and atherectomy
