oxygen; nutrients
a condition when the arteries that supply blood to the heart muscle become hardened and narrowed due to the buildup of cholesterol and plaque
coronary artery disease
a disease causing the left ventricle of the heart to become larger and thicker but does NOT cause the heart to work harder
athletic heart syndrome
a medical procedure to improve blood flow to the heart by bypassing the blocked artery with a graft of a vein taken from somewhere else in the body
CABG (Coronary Artery Bypass Graft)
a procedure that uses a special dye and X-rays to see how blood flows through the arteries in your heart
angiography
the primary function of the valves of the heart
prevent blood from back flowing
the medical term that means high blood pressure
hypertension

echocardiogram
known as the pacemaker of the heart; initiates the sinus rhythm, or normal electrical pattern, followed by contraction of the heart
SA node
an irregular heartbeat
arrhythmia
an abnormally slow heart rate, slower than 60 beats per minute
bradycardia
a method to bring an abnormal heart rhythm back to normal
cardioversion
records the heart's electrical activity
EKG (electrocardiogram)
the tendon-like cords of connective tissue that anchor the heart valves and prevent them from prolapse
chordae tendineae
a blowing, whooshing, or rasping sound heard during a heartbeat, caused by turbulent (rough) blood flow through the heart valves or near the heart
murmur
a heart rate is faster than 100 beats per minute
tachycardia
a procedure that is used to scar small areas in your heart that may be involved in your heart rhythm problems
cardiac ablation
an imaging method that uses powerful magnets and radio waves to create pictures of the heart
MRI (Magnetic Resonance Imaging)
an impact to the left chest that results in ventricular fibrillation, causing sudden cardiac arrest in an otherwise healthy heart
commotio cordis
a congenital condition that affects the protein in the body that helps build healthy connective tissue
Marfan syndrome
