Electrolyte imbalance is an important cause of QT dispersion

The impact of chronic hemodialysis on QT dispersion corrected QTdispersion and maximum QT-dispersion

Introduction: Sudden cardiac death is common in patients on hemodialysis and may occur in the immediate postdialysis period when ventricular premature complexes are common. QT dispersion reflecting hetovogelity in ventricle repolarization has been used for predicting patients with risk of malignant arrhythmia and sudden death. The purpose of the study was to assess the effect of hemodialysis on...

QT dispersion: time for an obituary?

Perhaps the believers and disbelievers represent two different poles of scientific and research attitude. Some believe that the original concept of QT dispersion is correct merely because the technology can be applied to existing ECGs, and that the results more or less frequently (irrespective of the reproducibility) statistically distinguish between clinically defined groups. Others point to t...

Measurement of QT dispersion.

Influenza A infection is an important cause of febrile seizures.

OBJECTIVES To compare the incidence of febrile seizures in children hospitalized for influenza A infection with parainfluenza and adenovirus infection and to examine the hypothesis that children hospitalized for influenza A (variant Sydney/H3N2) during the 1998 season in Hong Kong had more frequent and refractory seizures when compared with other respiratory viruses, including the A/Wuhan H3N2 ...

Endometriosis is an important cause of pelvic pain in adolescence.

OBJECTIVE despite endometriosis being a common disease, where early detection is key to preventing its progression, it is a condition often overlooked in adolescents. The aim of this study was to report the clinical characteristics of adolescent patients with endometriosis monitored in a tertiary hospital. METHODS a retrospective study of 394 patients undergoing surgery with a histological di...
