Abstract excerpt

BACKGROUND: Klinefelter syndrome (KS) is a sex chromosomal aneuploidy (47,XXY) affecting 1/660 males. Based on findings in Turner syndrome, we hypothesized that electrocardiogram (ECG) abnormalities would be present in males with KS. OBJECTIVE: To investigate ECGs in males with KS and compare with controls. METHODS: Case control study of 62 males with KS and 62 healthy males matched on age. The primary outcome...
