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.
Last year, Kate spent her first Easter as a mother of two at Bucklebury surrounded by the Middletons. I imagine it was a special one as it was Charlotte's first Easter, and George, then almost three, was old enough to enjoy an egg hunt. Prince William spent the weekend in Kenya attending the wedding of Jecca Craig.
