The human heart is an amazing biological machine controlled by an internal electrical system that produces about 100,000 beats a day. When abnormal electrical activity causes the heart to beat too quickly, too slowly, or erratically, the condition is called an arrhythmia . Although most arrhythmias are harmless, some can interfere with the heart's...

The heart is the first organ to form and begin working in humans. More than two decades of research have told us a lot about normal heart development. New diagnostic tools such as fetal echocardiography now allow doctors to find heart defects during pregnancy. In 1950, a child born with a congenital heart defect had only a 20 percent chance of...
