Searching for XYY males through electrocardiograms.
Price (1968) found that 300o of 20 males with 47,XYY karyotype had electrocardiograms (ECG) with prolonged P-R intervals. This prompted us to try to ascertain double-Y males by screening a large sample of clinically normal males through their ECG. From a file of about 30,000 ECGs, collected by one of us (M.F.L.) during the last 7 years, 34 were selected because (1) they were normal except for h...
متن کاملMaximum motor nerve conduction velocity in XYY males.
1. Maximum motor nerve conduction velocities were determined under standard conditions for the median and ulnar nerves in the right forearm in males: (a) from the general population, (b) from a subnormality hospital, and (c) in males with the XYY sex chromosome abnormality. Distal latencies for these nerves were also measured. 2. No significant differences in maximum peripheral motor nerve cond...
متن کاملTestosterone excretion rates in normal males and males with an XYY complement.
The incidence of males with an XYY chromosome complement in a maximum security hospital was found to be 3% (Jacobs et al., 1965). These males were exceptionally tall, and it was found that 1 in 3 of the men of over 6 ft. (183 cm.) in this hospital had an XYY chromosome constitution. This very high incidence in an over-6 ft. group was confirmed in a special hospital for the subnormal (Casey et a...
متن کاملBundle-Branch Block in a General Male Population
Background—Interest in bundle-branch block has focused primarily on its role as a predictor of mortality and coexisting cardiovascular diseases. Previous studies of prevalence, correlation to cardiovascular disease, and mortality have produced conflicting results. Methods and Results—We studied a random-sampled population of 855 men who were 50 years old in 1963 and followed them up for 30 year...

The XYY anomaly has been recognized since 1961 (Dunn et al, 1961; Sandberg et al, 1961), but in contrast to other sex chromosome aneuploidies, no consistent clinical syndrome associated with it has emerged. The phenotypes are wide ranging, but generally are tall normal males. Most interest in the syndrome has centred on the possibility that abnormal behaviour may be an associated feature. The f...
