An arrhythmia is a disorder of the heart rate (pulse) or heart rhythm, such as beating too fast (tachycardia), too slow (bradycardia), or irregularly.
|
|
An arrhythmia is an abnormality in the heart ' s rhythm, or heartbeat pattern. The heartbeat can be too slow, too fast, have extra beats, skip a beat, or otherwise beat irregularly.

Chronic mitral regurgitation is a long-term disorder in which the heart's mitral valve does not close properly, causing blood to flow backward (leak) into the upper heart chamber when the left lower heart chamber contracts. The condition is progressive, which means it gradually gets worse. See also: Acute mitral regurgitation

Heart failure, also called congestive heart failure, is a life-threatening condition in which the heart can no longer pump enough blood to the rest of the body.
|
|
Heart failure is a condition in which the heart has lost the ability to pump enough blood to the body ' s tissues. With too little blood being delivered, the organs and other tissues do not receive enough oxygen and nutrients to function properly.
|
|
"Heart failure" is a broad term- often used inter-changeably with "congestive heart failure" (CHF)- to describe the heart's inability to consistently pump enough blood to the body's organs and tissues. Heart failure occurs either from a structural or a functional abnormality.

Infectious endocarditis is an infection of the lining of the heart chambers and heart valves that is caused by bacteria, fungi, or other infectious substances. See also: Culture-negative endocarditis; Endocarditis.
|
|
|
The endocardium is the inner lining of the heart muscle, which also covers the heart valves. When the endocardium becomes damaged, bacteria from the blood stream can become lodged on the heart valves or heart lining.

Pulmonary edema is an abnormal build up of fluid in the lungs, which leads to swelling.
|
|
Pulmonary edema is a condition in which fluid accumulates in the lungs, usually because the heart ' s left ventricle does not pump adequately. The build-up of fluid in the spaces outside the blood vessels of the lungs is called pulmonary edema.

A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack."
|
|
The following Clinical Topic Tour provides an overview of stroke and was adapted from materials published by the National Institute of Neurological Disorders and Stroke and the Centers for Disease Control and Prevention.

A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow. A stroke occurs when blood flow is interrupted to part of the brain.
|
|
A stroke is an interruption of blood circulation to the brain causing a neurologic deficit reflecting the area of the brain affected. Stroke can be ischemic or hemorrhagic. 1 Ischemic stroke is most prevalent.
|
|
Stroke is an increasing public health concern throughout the world as the leading cause of long-term disability. There is estimated to be over 3.5 million survivors of stroke in the United States.
|
|
|
A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow. A stroke occurs when blood flow is interrupted to part of the brain.
|
|
There are various clinical and pathological subtypes of stroke, and identification of the subtype is necessary for correct management. Investigations Imaging Brain imaging should be performed within the first 48 hours of the onset of stroke (see below), to determine whether the stroke is haemorrhagic or ischaemic and to exclude other causes (e.g. tumour).

|
Stroke, or cerebrovascular accident (CVA), is the third leading cause of death (after heart disease and cancer) in the United States and the industrialized countries of the world. The term " stroke, " which comes from subjects being suddenly " struck down " with neurological deficits, is commonly used by both professional and lay groups.
|
|
|
Cerebrovascular accident (CVA) is the medical term for what is commonly termed a stroke. It refers to the injury to the brain that occurs when flow of blood to brain tissue is interrupted by a clogged or ruptured artery, causing brain tissue to die because of lack of nutrients and oxygen.
|
|
|
A stroke, also called a cerebral infarction, is a life-threatening condition marked by a sudden disruption in the blood supply to the brain. A disruption in the blood supply to the brain starves the brain of oxygen-rich blood and causes the nerve cells in that area to become damaged and die within minutes.
|
|
A stroke, also called a cerebral vascular accident (CVA), is the sudden death of cells in a specific area of the brain due to inadequate blood flow. A stroke occurs when blood flow is interrupted to a part of the brain, either when an artery bursts or becomes closed when a blood clot lodges in it.
|
|
|
Stroke is the common name for the injury to the brain that occurs when the flow of blood to brain tissue is interrupted by a clogged or burst artery. Arterial blood carries oxygen and nutrition to the cells of the body.
