brady- | slow |
bradycardia | Cardiac arrhythmias that are characterized by abnormally slow heart rate, usually below 50 beats per minute in adults. |
bundle branch block | A type of heart block where the electrical signals to the ventricles are interrupted at the Bundle of HIS, preventing the simultaneous depolarization of the two ventricles. |
bundle of His | Cells that conduct electrical impulses from the atrioventricular node to the ventricles. |
calcium channel blockers | A class of drugs that inhibit calcium influx through cellular membranes. Used to reduce cardiac workload to treat hypertension or angina. |
capillaries | The minute blood vessels that deliver oxygen and nutrients to the cells. They connect the arterioles and venules. |
cardi/o | heart |

cardiac catheterization | A diagnostic procedure for creating an angiogram using a contrast agent. Also used for treating blocked arteries. |
cardiology | The study of the heart, its physiology, and its functions. |
cardiomegaly | An enlargement of the heart. Multiple causes. |
cardiomyopathy | Disease of the heart muscle. Can be congenital, or acquired from infections, alcoholism, thyroid disease, toxic drugs. |
cardiovascular system | The heart and the blood vessels by which blood is pumped and circulated through the body. |
carditis | Inflammation of the heart. Three types are pericarditis (pericardium), myocarditis (heart muscle) and endocarditis (endocardium). |
carotid arteries | The two major arteries of the neck that supply blood to the head; each artery has two branches, internal and external. |

congenital heart defect | An abnormality that is present at birth and can affect the structure and function of an infant's heart. |
congestive heart failure | The heart isn't able to pump sufficient blood. Typical causes are coronary artery disease, high blood pressure, diabetes and obesity. |
