Future heart defibrillators could save lives with light pulses
Scientists think that beams of red light could restore normal heartbeat functions in humans, replacing the use of painful electric shocks. Researchers have already tested this on animals and hope to make — incredibly — an optical defibrillator. Biomedical engineering professor Natalia Trayanova, based at John Hopkins University said that with this tech, "light will be given to a patient who is experiencing cardiac arrest, and we will be able to restore the normal functioning of the heart in a gentle and painless manner."
