1

Aneurysm

Localized abnormal dilation of a vessel, usually an artery

2

Angina

Mild to severe suffocating pain that typically occurs in the chest and is caused by inadequate blood flow to the myocardium also called angina pectoris

3

Arrhythmia

Irregularity in the rate or rhythm of the heart; also dysrhythmia

4

Bradycardia

Arrhythmia in which the heart beat abnormally slowly, usually fewer than 60 beats per minute in a resting adult

5

Fibrillation

Arrhythmia in which there is an abnormally rapid, uncorrelated quivering of the myocardium myocardium that can affect the Atria of the ventricles

6

Heart block

Arrhythmia in which there is interference with the abnormal transmission of electrical impulses from the SA node to the purkinje fibers

7

Arteriosclerosis

Hardening and narrowing of an artery along with the loss of its elasticity

8

Tachycardia

Arrhythmia in which there is a fast but regular rhythm, with the heart possibly beating up to 200 beats/minute

9

Atherosclerosis

Form of arteriosclerosis characterized by the deposit of plaques containing cholesterol and lipids that narrows the lumen in the arteries

10

Carotid artery disease

Narrowing of the carotid arteries, usually caused by atherosclerosis; may eventually lead to thrombus formation and stroke

11

Bruit

soft blowing sound heard on auscultation, associated valvular action or with the movement of blood as it passes and obstruction or both also called murmur

12

Cardiomyopathy

Disease or weakening of heart muscle that diminishes cardiac function

13

Coarctation

Narrowing of a vessel, especially the aorta

14

Embolism

Condition in which a mass commonly a blood clot becomes lodged in a blood vessel, obstructing blood flow

15

Hyperlipidemia

Excessive amounts of lipids cholesterol, phospholipids, and triglycerides in the blood

16

Hypertension(HTN)

Elevated blood pressure persistently higher than 140/90 mm hg

17

Hypotension

Low blood pressure persistently lower than 90/60 mm Hg

18

Infarction

Localized tissue necrosis due to the cessation of blood supply

19

Ischemia

Local, temporary deficiency of blood supply to an organ or tissue due to circulatory obstruction

20

Mitral valve prolapse (MVP)

Structural defect in which the mitral (bicuspid) valve leaflets prolapse into the left atrium during ventricular contraction (systole), resulting in incomplete closure and backflow of blood

21

Palpitation

Sensation of an irregular heartbeat, commonly described as pounding, racing, skipping a beat, or flutter

22

Phlebitis

Inflammation of a deep or superficial vein of the arms or legs (more commonly the legs)

23

Syncope

Partial or complete loss of consciousness that is usually caused by a decreased supply of blood to the brain; also called fainting

24

Thrombosis

Abnormal condition in which a blood clot develops in a vessel and obstructs it at the site of its formation

25

Deep vein thrombosis (DVT)

Blood clot that forms in the deep veins of the body, especially those in the leg or thighs; also called deep venous thrombosis

26

Defibrillation

Electrical shock delivered randomly during the cardiac cycle to treat emergency life- threatening arrhythmias

27

Cardioversion

Defibrillation technique using low energy shocks to treat an arrhythmia (atrial fibrillation, atrial flutter , or ventricular tachycardia), and is usually synchronized with the large R waves of the ECG complex to restore normal heart rhythm

28

Sclerotherapy

Injection of a chemical irritant (sclerosing agent) into a vein to produce inflammation and fibrosis that destroys the lumen of the vein

29

Thrombolysis

Destruction of a blood
clot using anticlotting called clot-busters, such as tissue plasminogen activator

30

Angioplasty

Any Endovascular procedure that reopens narrowed blood vessels and restores forward blood flow
