Question 1

Angina pectoris

Answer 1

Chest pain caused by insufficient blood flow to the heart

Question 2

Arteriosclerosis

Answer 2

Hardening or fibrosis of the arteries

Question 3

Atherosclerosis

Answer 3

Accumulation of fatty deposits in the walls of arteries

Question 4

AV

Answer 4

Atrioventricular, as in the AV node

Question 5

Chronic heart failure CHF

Answer 5

Heart disease caused by weakness of the contract out force of the myocardium

Question 6

Conduction system

Answer 6

Specialized cardiac tissue that transmits electrical impulses and regulates the activity of the heart

Question 7

Coronary artery disease CAD

Answer 7

Disease of the coronary arteries the decreases blood flow to the heart

Question 8

Depolarization

Answer 8

The decrease in electrical potential across the cell membrane that results in excitation and generation of an action potential

Question 9

Electrocardiogram

Answer 9

Recording of the electrical activity of the heart

Question 10

Ischemia

Answer 10

Condition of insufficient tissue blood flow

Question 11

Myocardial infarction

Answer 11

Sudden death of an area of heart muscle, commonly referred to as a heart attack

Question 12

Myocardium

Answer 12

The muscular layer of the heart

Question 13

Repolarization

Answer 13

Return of the electrical potential across the cell membrane to its resting state following depolarization

Question 14

SA

Answer 14

Sinoatrial, SA node
