specialized muscle fibers connecting the atria with the ventricles and transmitting electrical impulses between them.
atrioventricular node (AV node)
specialized tissue in the wall between the atria. Electrical impulses pass from the pacemaker (SA node) through the AV node and the atrioventricular bundle or bundle of His toward the ventricles.
smallest blood vessel. Materials pass to and from the bloodstream through the thin capillary walls.
relaxation phase of the heartbeat. From the Greek
flow of blood from the heart to the lungs and back to the heart.
partition or wall dividing a cavity, such as between right and left atria (interatrial septum) and right and left ventricles (interventricular septum)
sinoatrial node (SA node)
pacemaker of the heart
flow of blood from body tissue to the heart and then from the heart back to body tissues

inflammation of the inner lining of the heart
local widening (dilation) of an arterial wall
high blood pressure
an ECG device is worn during a 24-hour period to detect cardiac arrhythmias.
exercise tolerance test (ETT) determines the heart's response to physical exertion (stress)
technique using lower energy to treat atrial fibrillation, atrial flutter, and supraventricular tachycardia
percutaneous coronary intervention (PCI)
balloon-tipped catheter is inserted into a coronary artery to open the artery; stents are put in place.
