The Heart And Heart Disease Chapter 14

Front 1

Arrhythmia

Back 1

Abnormal rhythm of the heart beat. Dysrhythmia

Front 2

Atherosclerosis

Back 2

Hardening of the arteries due to the deposit of yellowish, fatlike material in the lining of these vessels

Front 3

Atrium

Back 3

One of the two upper chambers of the heart.

Front 4

Bradycardia

Back 4

Heart rate of less than 60 beats per minute.

Front 5

Coronary

Back 5

Referring o the heart or to the arteries supplying blood to the heart.

Front 6

Coronary Thrombosis

Back 6

Thrombus formation results in a life-threatening condition. Sudden occlusion of coronary vessel with complete obstruction of blood flow is called a heart attack.

Front 7

Diastole

Back 7

Relaxation phase of the cardiac cycle/ diastolic.

Front 8

Echocardiograph

Back 8

Instrument to study the heart by means of ultrasound. The record produced is an echocardiogram.

Front 9

Electrocardiography

Back 9

Instrument to study the electrical activity of the heart; record made is an electrocardiogram.

Front 10

Endocardium

Back 10

Membrane that lines the heart chambers and covers the valves.

Front 11

Epicardium

Back 11

Membrane that forms the outermost layer of the heart wall and is continuous with the lining of the fibrous pericardium; visceral pericardium

Front 12

Fibrillation

Back 12

Very rapid, uncoordinated beating of the heart.

Front 13

Infarct

Back 13

Area of tissue damaged from lack of blood supply caused by a vessel blockage

Front 14

Ischemia

Back 14

Lack of blood supply to an area

Front 15

Murmur

Back 15

Abnormal heart sound

Front 16

Myocardium

Back 16

Middle layer of the heart wall; heart muscle

Front 17

Pacemaker

Back 17

Sinoatrial node of the heart; group of cells or artificial device that sets the rate of heart contractions

Front 18

Pericardium

Back 18

Fibrous sac lines with serous membrane that encloses the heart

Front 19

Plaque

Back 19

A patch or flat area; fatty material that deposits in vessel linings in atherosclerosis

Front 20

Septum

Back 20

Dividing Wall, as between the chambers of the heart or the nasal cavities

Front 21

Stenosis

Back 21

Narrowing of a duct or canal

Front 22

Systole

Back 22

Contraction phase of the cardiaccycle/ systolic

Front 23

Tachycardia

Back 23

Heart rate more than 100 beats per minute

Front 24

Valve

Back 24

Structure that prevents fluid from flowing backward as in the heart, veins and lymphatic vessels

Front 25

Ventricle

Back 25

Cavity or chamber one of the two lower chambers of the heart
