Association of short PR interval, long QT interval and sudden cardiac death in a young male.
A 26-year-old man came to our hospital for paroxysmal palpitations accompanied by profuse sweating, dry heaves, and considerable psychomotor agitation unrelated to effort (sudden onset during physiological sleep). He was transferred to the recovery unit for assessment and symptom management. During the patient’s stay in the unit, his overall condition deteriorated unexpectedly, ventricular tach...
متن کاملGenetic determinants of QT interval variation and sudden cardiac death.
Electrocardiographic QT interval prolongation or shortening is a risk factor for sudden cardiac death. The study of Mendelian syndromes in families with extreme long and short QT interval duration and ventricular arrhythmias has led to the identification of genes encoding ion channel proteins important in myocardial repolarization. Rare mutations in such ion channel genes do not individually co...

متن کاملSudden infant death syndrome, long QT interval, and Helicobacter pylori.
The report by Vermeer and colleagues 1 that vitamin K may be important in the causation of metabolic bone disease is interesting, but there is an alternative hypothesis that could also explain some of the apparently vitamin K mediated bone eVects. Vitamin B-6 is an essential cofactor for the enzyme ornithine decarboxylase which is the rate limiting enzyme in the formation of putrescine which re...
متن کاملProlonged QT interval and cardiac arrhythmias in two neonates: sudden infant death syndrome in one case.
Two neonates with arrhythmias and the long QT syndrome are described. The arrhythmias were detected in utero and both infants were apparently well after birth. The first infant, although well, had a bradycardia for the first 9 days of life. A normal heart rate was documented at 10 days but a prolonged QT interval was not appreciated on the ECG. He was discharged from hospital but died suddenly ...
