New cyber heart model recalls da Vinci's sketches

LONDON (Reuters) - Five centuries after Leonardo da Vinci's intricate drawings transformed understanding of the human heart, a new computer model promises to do the same for modern-day cardiac care, experts say.

The model -- so realistic its four chambers beat in the same asymmetrical rhythm on screen as does a real heart in the human body -- is the work of three British doctors who say the creation will improve both training and care during surgery.
