Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [2] as blood vessels dilate in an attempt to increase
Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components.
In heat exhaustion, the core body temperature rises to between 37 °C and 40 °C (98.6 °F and 104 °F). To dissipate heat, blood flow to the skin can increase up to 8 liters per minute, accounting for a significant proportion of the cardiac output. This increase in peripheral circulation leads to a reduction in central blood volume—the ...
A stroke occurs when blood flow to the brain becomes blocked or if there is sudden bleeding in the brain. ... This test evaluates and records your heart’s electrical signals to check if your ...
Otherwise an electrocardiogram, blood work to check the heart, and urine testing for signs of muscle breakdown may be performed. [9] Management may involve resuscitation, pain medications, wound management, and heart rhythm monitoring. [9] Electrical injuries affect more than 30,000 people a year in the United States and result in about 1,000 ...
The mechanism of the injuries may include electrical injury, burns from heat, and mechanical trauma. [1] Diagnosis is typically based on history of the injury and examination. [1] Prevention includes avoiding being outdoors during a thunderstorm, and sheltering in a fully enclosed structure (such a closed building or metal car).
[1] [11] Later research revealed the link between neurological signs such as visual loss and increased heat production and Uhthoff's belief that exercise was the etiology of visual loss was replaced by the conclusions of these later researchers stating that heat was the prime etiology.
