What Does LED Stand for in Cardiology?

LED stands for light-emitting diode. LEDs are a powerful light source 5 times greater than the average high-powered light source. In cardiology, LEDs play a major role in the function of pacemakers. LEDs are found in equipment used to measure blood flow and to examine blood vessels.

  1. Significance

    • According to laboratory research conducted at the Midwest Athletes Against Childhood Cancer Fund Research Center, "LEDs also grow human muscle and skin cells up to five times faster than normal."

    Function

    • Light has long been thought to be a healing agent in the body. The laser lighting allows your doctor to inspect your blood vessels, and the heart itself.

    Accelerated Healing

    • Harry T. Whelan, MD, professor of neurology, pediatrics, and hyperbaric medicine at the Medical College of Wisconsin, says, "The near-infrared light emitted by these LEDs seems to be perfect for increasing energy inside cells. This means whether you're on Earth in a hospital, working on a submarine under the sea, or on your way to Mars inside a spaceship, the LEDs boost energy to the cells and accelerate healing."

    Considerations

    • The light source in LED allows doctors to explore your arteries. LEDs enable doctors to perform angioplasty surgery that will unclog your arteries.

    Location

    • LEDs are built into computers and other medical examination equipment.
