Short QT syndrome is a genetic disease of the electrical system of the heart. It consists of a constellation of signs and symptoms, consisting of a short QT interval on an EKG (≤ 300 ms) that does not significantly change with heart rate, tall and peaked T waves, and a structurally normal heart. Short QT syndrome appears to be inherited in an autosomal dominant pattern, and a few affected families have been identified.

Famous quotes containing the words syndrome and/or short:
“Women are taught that their main goal in life is to serve othersfirst men, and later, children. This prescription leads to enormous problems, for it is supposed to be carried out as if women did not have needs of their own, as if one could serve others without simultaneously attending to ones own interests and desires. Carried to its perfection, it produces the martyr syndrome or the smothering wife and mother.”
—Jean Baker Miller (20th century)
“Language was not powerful enough to describe the infant phenomenon. Ill tell you what, sir, he said; the talent of this child is not to be imagined. She must be seen, sirseento be ever so faintly appreciated.... The infant phenomenon, though of short stature, had a comparatively aged countenance, and had moreover been precisely the same agenot perhaps to the full extent of the memory of the oldest inhabitant, but certainly for five good years.”
—Charles Dickens (18121870)
