| Aneurysms | Localized dilation in the wall of the blood vessel cause by atherosclerosis or hypertension, and less commonly by congenital weakness |
| Angina pectoris | Paroxysmal thoracic pain and choking caused by decreased oxygen(anoxia) of the myocardium |
| Arteriosclerosis | Arterial disorder characterized by thickening, loss of elasticity, and calcification of arterial walls resulting in decreased blood supply |
| Bradycardia | Slow rhythm characterized by a heartbeat <60 BPM |
| Cardioversion | Restoration of the heart's normal sinus rhythm by delivery of a synchronized electric shock through to metal panels placed on the patient's chest |
| Coronary artery disease(CAD) | Variety of conditions that obstruct blood flow in the coronary arteries |
| Defibrillation | The termination of ventricular fibrillation by delivering a direct electrical counter shock to the pericardium |
| Dysrhythmia | Any cardiac rhythm that deviates from normal sinus rhythm; also called arrhythmia |
| Embolus | A foreign object, quantity of air or gas, tumor or piece of the thrombus that circulates in the blood stream until it becomes lodged in the blood vessel |
| Endararterectomy | Surgical removal of the intimal lining of the artery |
| Heart failure | Syndrome characterized by circulatory congestion due to the heart's inability to act as an effective pump |
| Hypoxemia | Abnormal deficiency of O2 in the arterial blood |
| Intermittent claudication | Weakness in the legs caused by cramps like pain in the calves; caused by poor arterial circulation of the blood in the leg muscles |
| Ischemia | Decreased blood supply to a body organ or part; often marked by pain or organ dysfunction |
| Myocardial infarction | occlusion of major coronary artery or one of its branches; caused by atherosclerosis or an embolus resulting in necrosis of a portion of cardiac muscle |
| Occlusion | obstruction or closing off of the canal, vessel, or passage of the body |
| Orthopnea | abnormal condition in which person must sit or stand in order to breathe deeply or comfortably |
| Peripheral | Pertaining to the outside, surface, or surrounding area |
| Pleural effusion | Abnormal accumulation of fluid in the thoracic cavity between the visceral and parietal pleurae |
| Polycythemia | Abnormal increase in the number of red blood cells in the blood |
| Pulmonary edema | Accumulation of extra vascular fluid in the lung tissue and alveoli; caused most commonly by left-sided heart failure |
| Tachycardia | Abnormal condition in which the myocardium beats regularly, but at the rate >100 BPM |
| Mediastinum | The mass of organs and tissues separating the lungs; contains trachea and esophagus |
| Apex | Narrow part; slightly to the left between 5th and 6th ribs near diaphragm |
| Base | lies superior And beneath the 2nd rib |
| Pericardium | Outermost layer of the heart |
| Myocardium | Forms the bulk of the heart wall and is the thickest and strongest layer of the heart |
| Endocardium | innermost layer, thin layer of connective tissue |
| Septum | heart division of left and right by a muscular partition |
| Right Atrium | upper right chamber |
| Right Ventricle | Lower right chamber |
| Left Atrium | upper left chamber |
| Left Ventricle | Lower left chamber |
| Right Atrium | receives deoxygenated blood from the entire body |
| Right Ventricle | Receives deoxygenated blood from right atrium |
| Right Ventricle | pumps blood to the lungs VIA pulmonary artery to release carbon dioxide and receive oxygen |
| Left Atrium | receives oxygenated blood from the lungs VIA the pulmonary veins |
| Left Ventricle | oxygenated blood from the left atrium |
| Left Ventricle | thickest, most muscular section of the heart and pumps the oxygenated blood through out the aorta to all parts of the body |
| heart function | right side receives deoxygenated blood and pumps it to the lungs |
| Heart function | left side receives oxygenated blood from the lungs and pumps it throughout the body |
