A step toward understanding how hibernation protects hearts

Wintry weather means hats and scarves for some mammals, and hibernation for others. Hibernation dramatically lowers body temperatures, heart rates and oxygen consumption—things that would be fatal to other animals. A team ...

Low-power chip for intra-cardiac ventricular fibrillation detection

Imec demonstrated a low-power (20µW), intra-cardiac signal processing chip for the detection of ventricular fibrillation at this week's International Solid State Circuits Conference (ISSCC 2013) in San Francisco with Olympus. ...

Can chaos theory help predict heart attacks?

Chaos models may someday help model cardiac arrhythmias -- abnormal electrical rhythms of the heart, say researchers in the journal CHAOS, which is published by the American Institute of Physics.
