Jan Refsdahl's heart stopped for 4 hours when he fell into icy sea off Bergen, Norway - and he made a full recovery. The heart is essentially a muscle (a little larger than the fist.) Like any other muscle in the human body, it contracts and expands. Unlike skeletal muscles, however, the heart works on the 'All-or-Nothing Law.' That is, each time the heart contracts it does so with all its force. In skeletal muscles, the principle of 'gradation' is present. The pumping of the heart is called the Cardiac Cycle, which occurs about 72 times per minute. This means that each cycle lasts about eight-tenths of a second. During this cycle the entire heart actually rests for about four-tenths of a second. See http://worldinvisible.com/apologet/humbody/heart.htm Feb 13 01, 9:34 AM

The ancient egyptians believed that the persons soul or 'Ka' resided in the heart and so when they mummified a body the heart was preserved in a seperate jar so that it would be there for the person to use upon his ressurection. They however yanked out the brain through the nose and threw it away as they considered it a useless organ. Mar 09 01, 12:58 AM
