A pulse that is too rapid or too slow may reduce the amount of blood the heart can pump and lead to syncope (fainting; Emboli to the brain (stroke) or elsewhere - rare, but often treated with anticoagulation to reduce this risk.

Patients with atrial fibrillation and flutter can live a normal life for many years as long as the arrhythmia is controlled and serious blood clots are prevented.

Fainting is a temporary loss of consciousness due to a drop in blood flow to the brain. The episode is brief (lasting less than a couple of minutes) and is followed by rapid and complete recovery. You may feel lightheaded or dizzy before fainting. A longer, deeper state of unconsciousness is often called a coma.

Fainting is a temporary loss of consciousness, weakness of muscles, and inability to stand up, all caused by sudden loss of blood flow to the brain. Fainting is a relatively common symptom caused by a variety of problems relating to changes in blood pressure.

Fainting is loss of consciousness caused by a temporary lack of oxygen to the brain. Known by the medical term " syncope, " fainting may be preceded by dizziness , nausea, or a feeling of extreme weakness.

Syncope, or fainting, is a temporary loss of consciousness, usually caused by decreased blood flow to the brain . Syncope is a symptom, rather than a disease itself, and has many causes.

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.
