CH 8 HEART vocab MEL

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
