Hearing impairment
|
|
Hearing impairment Complete or partial loss of the ability to hear, caused by a variety of injuries or diseases, including congenital causes. Limitations, including difficulties in understanding language or other auditory messages and/or in production of understandable speech, are possible.
RELATED TERMS--------------------------------------
Congenital
Present at birth.
SIMILAR TERMS--------------------------------------
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Heart attack
Heart attacks occur when a coronary artery is completely blocked and a portion of the heart muscle is left without a supply of oxygenated blood. If the portion is large enough, the heart attack may be deadly.
Heart Attack (myocardial infarction)
Permanent damage to the heart muscle caused by a lack of blood supply to the heart for an extended time period. The severity of damage varies from normal, mild, to severe.
Heart block
Interrupted electrical impulse to heart muscles.
Heart Block
An arrhythmia. The electrical current is slowed between the atria and ventricles. In more severe cases, conduction is blocked completely and the atria and ventricles beat independently.
Heart disease
Usually, heart disese occurs due to inadequate blood flow to the hear muscle. This occurs when the arteries that supply the heart muscle (the coronary arteries) become partially or completely blocked. Obese people are at increased risk of heart disease due to their higher rates of hypercholesterolemia, diabetes and hypertension.
Heart failure
Inability of the heart to adequately pump blood.
Heart Failure (congestive heart failure, CHF)
A chronic, progressive disease in which the myocardium (heart muscle) weakens and can not pump blood efficiently. Fluid accumulates in the lungs, hands, ankles, or other parts of the body.
Heart Hospital Of Bakersfield L.L.C.

Heart Hospital of South Dakota

Heart Lung Bypass Machine
A machine that oxygenates the blood and circulates it throughout the body during surgery.
Heart Monitor
An electrocardiography machine designed to monitor heart function continuously.
Heart of America Medical Center
Heart of America Medical Center is a hospital in Rugby, North Dakota (USA).
Heart of Tampa
Heart of Tampa is a hospital in Hudson, Florida (USA).
Heart Surgery
Heart surgery is any surgery, which involves the heart or heart valves.
Heart Valve
There are four valves in the heart: the tricuspid and the mitral valve, which lie between the atria and ventricles and the pulmonic and aortic valves which lie between the ventricles and the blood vessels leaving the heart. The heart valves help to maintain one-way blood flow through the heart.
Heart valve prolapse
A condition of the heart valve in which it is partially open when it should be closed.
Heart-lung machine
A machine that performs for the heart during open heart surgery.
Heartburn
Substernal pain or burning sensation, usually associated with regurgitation of gastric juice into the esophagus.

The Heartland Behavioral Health Services is a hospital in Nevada, Missouri, United States.
Heartland Health Care Center
The Heartland Health Care Center is a hospital in Pittsburgh, Pennsylvania, United States.
Heartland Regional Medical Center
Heartland Regional Medical Center is a hospital in Saint Joseph, Missouri (USA).
PREVIOUS AND NEXT TERMS--------------------------------------
Hormone Releasing Factors
Hormones released from the hypothalamus that directly affect the pituitary and initiate the release of other hormones into the bloodstream. Many hormone releasing factors use cyclic AMP as their secondary messengers.
Hyperinsulinemia
The excess production of insulin. This is usually a consequence of insulin resistance in which the cells do not respond to insulin to reduce blood glucose levels.
Hypothalamus
The portion of the brain's limbic system that integrates incoming information, and either increases or decreases the release of certain hormones that instruct the pituitary gland to release hormones.
Human Immunodeficiency Virus (HIV)
A virus that steadily weakens the body's defense (immune) system until it can no longer fight off infections such as pneumonia, diarrhea, tumors and other illnesses. All of which can be part of AIDS (Acquired ImmunoDeficiency Syndrome). Unable to fight back, most people die within three years of the first signs of AIDS appearing. Most of all HIV infections have been transmitted through unprotected sexual intercourse with someone who is already infected with HIV. HIV can also be transmitted by infected blood or blood products (as in blood transfusions).
Hypertension
Higher blood pressure than normal. Diastolic blood pressure from 90 to 99 mm HG is considered mild hypertension; 100–109, moderate hypertension; and 110 or greater, severe hypertension. Systolic blood pressure from 140 to 159 mm HG is considered mild hypertension; 160–179, moderate hypertension; and 180 or greater, severe hypertension.
Hearing impairment
Hemiplegia
Paralysis of one side of the body as a result of injury to neurons carrying signals to muscles from the motor areas of the brain.
Hyperopia
Hyperopia (or more rarely, hypermetropia), also known as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina.
Hemophilia
A genetic blood disorder, almost always in males, in which blood does not clot properly as a result of an enzyme deficiency.
Hallucination
A false perception of something that is not really there. Hallucinations may be seen, heard, touched, tasted, or smelled by the ill individual. In schizophrenia, auditory hallucinations are most common.
Hydrocortisone
A hormone secreted by the adrenal cortex which affects metabolism.
