Glossary

Here are some common words that are used in cardiac Management which is very useful to understand in the layman's terms.

H
Heart attack
Irreversible damage to an area of the heart muscle caused by an insufficient oxygen supply; also called "myocardial infarction" or " MI"

Heart failure
A condition in which the heart muscle is unable to pump enough blood to maintain normal circulation; this results in build-up of fluid in the body (especially in the feet, ankles, and lungs); also called "congestive heart failure."

Heart rate
Number of contractions (beats) of the hear t per minute.

Holter monitor
A procedure involving the recording on magnetic tape of the heart's electrical signals as they are emitted during an ECG taken over a period of 24 hours; the signals are replayed to detect changes that might go unnoticed in the short time of an ordinary ECG recording; also called "ambulatory ECG monitoring."

I
Infarction
Death of living cells as results of an insufficient supply of blood and oxygen; see heart attack

Ischemia
Local, usually temporary deficiency in the supply of oxygen to some part of the body; see myocardial ischemia and residual myocardial ischemia.

L
Left main coronary artery
The major coronary artery supplying the left ventricle with blood and oxygen.

Left ventricular dysfunction
An impairment in the normal functioning of the left ventricle.

Lumen
Central channel of a blood vessel, through which the blood flows.


M
Mitral valve
The heart valve between the left atrium and left ventricle.

Myocardial ischemia
Lack of an adequate supply of oxygen to the heart muscle
