arrhythmia
Irregular heart beat
arteriosclerotic heart disease
arteriosclerosis or atherosclerosis of coronary arteries
bradycardia
abnormally slow heart rate below 60 beats per minute
cardia catheterization
passage of thin tube through veins or arteries leading into heart for diagnostic or therapeutic purposes
cardiac arrest
complete stoppage of electrical signals and contractions in the heart
congestive heart failure
condition that develops when heart muscle is not able to pump blood forcefully enough, reducing blood flow to body; results in weakness, dyspnea, and edema

hypotension
decrease in blood pressure

myocardial infarction
heart attack: infarct of heart muscle cause by occlusion of one or more of coronary arteries
occlusion
blockage of blood vessel or other hollow structure
pace maker
electrical device that artificially stimulates contraction of heart muscle
peripheral vascular disease
disease of blood vessel away from central region of body
stenosis
narrowing of a passage of orifice
stent
tube place within blood vessel or duct to widen lumen
tachycardia
abnormal fast heart rate, more than 100 beats per minute
thrombosis
the formation or presence of blood clot within the vascular system
thrombus
