A specialist in cardiac electrophysiology is known as a cardiac electrophysiologist, or (more commonly) simply an electrophysiologist. Cardiac electrophysiology is considered a subspecialty of cardiology in most countries and usually requires two or more years of fellowship training beyond a general cardiology fellowship.
PHOTOS: William and Kate's childhood pictures. But as with her first pregnancy, Duchess Kate is suffering from hyperemesis gravidarum, a very acute morning sickness, which required an in-patient stay at King Edward VII's Hospital during her pregnancy with Prince George. So far with this pregnancy, however, the Duchess is being treated at home.
Kate has occassionally had growing pains, but none lasting that long. As a kid I remember having them but they rarely lasted more than a week. I would have the ped check again. Could she be faking it? My kids often complain of aches and pains and tired legs only to turn around and run at the park.
