incision of a vein
phlebotomy
thromb/o
clot
fibrous, membrane sac that surrounds the heart
pericardium

diastol
contraction of the heart; pulmonary and aortic open; tricuspid and mitral closed
systole
sensitive tissue in right atrium wall that begins the heartbeat
sinoatrial node
failure of proper conduction of impulses from the SA node through the AV node to the atrioventricular bundle
bradycardia
very rapid, random, inefficient, and irregular contractions of the heart
fibrillation

coronary artery
chest pain at rest relieved with nitroglycerin
angina
drops blood pressure and increases blood flow to the heart

decreased oxygen in the blood
hypoxemia
regularity of the P, QRS, and T-waves
normal sinus rhythym
