AV bundle (Bundle of His) a band of fibers that transmit impulses from the artioventricular (AV) node to the top of the interventricular septum. It divides into the right and left bundle branches, which descend along the two sides of the septum; the bundle of His.
capillary /capillaries A microscopic blood vessel through which materials are exhanged between the blood and the tissue.
diastole The relaxation phase of the hearbeat cycle when the chamber fills with blood; adjective, diastolic
inferior vena cava Tjhe large inferior vein that brings bood back to the right atrium of the heart from the lower part of the body
Pulmonary valve The valve at the entrance to the pulmonary artery
percardium The fibrous sac that surrounds the heart
myocardium The thick middle layer of the heart wall composed of cardiac muscle.
mitral valve The valve between the left atrium and the left ventricle; the left AV valve or biscuspid valve.
sinoatrial (SA) node A small mass in the upper part of the right atrium that initiates the impulsew for each heartbeat; the pacemaker.
superior vena cave the large superior vein that brings deoxgenated blood back to the right atrium from the upper part of the body.

arteriorrhexis rupture of an artery
arteriotomy incision of an artery
CAD Coronary Artery Disease
Creatine Kinase (CK) an enzyme normal to muscle cells
How is a MI diagnosed? electrocardiogrphy and assays for specific substances in the blood.
Congenital Defect any defect that is present at birth
aneurysm a localized abnormal dilation of blood vessel, usually an atery, caused by weakness of the vessel wall; may eventually burst
angina pectoris a felling of constriciton around the heart or pain that may readiate to the left arm or shoulder, usually brought on by exertion; caused by insufficient blood supply to the heart
arrhythmia any abnormality in the rate or rhythm of the heartbeat (literally "without rhythm"; note double r). Also called dysrhythmia
atherosclerosis the development of fatty fibrous patches (plaques) in the lining of arteries, causing narrowing of the lumen and hardening of the vessel wall. most common hardening of the arteries. Root ather/o means "porridge" or "gruel."
vradycardia a slow heart reate, of less than 60 beats per minute
cerebrovascular accident (CVA) Sudden damage to the brain resulting from reduction of blood flow. Causes include atherosclerosis, emblolism, thrombosis, or hemorrhage from a ruptured aneurysm; commonly called stroke.
