Answer

Findings on physical examination usually do not indicate a diagnosis of LQTS, although some patients may present with excessive bradycardia for their age, and some patients may have hearing loss (congenital deafness), indicating the possibility of Jervell and Lange-Nielsen syndrome. Skeletal abnormalities, such as short stature and scoliosis are seen in the LQT7 type (Andersen syndrome), and congenital heart diseases, cognitive and behavioral problems, musculoskeletal diseases, and immune dysfunction may be seen in those with LQT8 type (Timothy syndrome).
