Prevalence of the QT interval prolongation and its risk factors in hospitalized geriatric patients: findings of a single center cross-sectional study in Pakistan [PDF]
Background and objectives Geriatric inpatients are particularly susceptible to Torsades de Pointes (TdP) because they are usually polymorbid and often take QT-prolonging drugs.

A Study on the Diurnal Variation of Ventricular Repolarization Parameters in Patients with Obstructive Sleep Apnea [PDF]
BackgroundObstructive sleep apnea hypopnea syndrome (OSAHS) is a common sleep breathing disorder. More and more studies have shown that OSAHS has a significant correlation with cardiovascular disease.

Background: Fluoroquinolones, crucial components of treatment regimens for drug-resistant tuberculosis (TB), are associated with QT interval prolongation and risks of fatal cardiac arrhythmias. However, few studies have explored dynamic changes in the QT

The Measurement of the QT Interval [PDF]
The evaluation of every electrocardiogram should also include an effort to interpret the QT interval to assess the risk of malignant arrhythmias and sudden death associated with an aberrant QT interval. The QT interval is measured from the beginning of the QRS complex to the end of the T-wave, and should be corrected for heart rate to enable comparison

Corrected QT interval and QT dispersion in temporal lobe epilepsy
Background Cardiac arrhythmias are expected among patients with epilepsy due to the effect of anti-epileptic drugs. Temporal lobe epilepsy also causes autonomic seizures that may affect heart rhythm.

QT is longer in drug-free patients with schizophrenia compared with age-matched healthy subjects. [PDF]
The potassium voltage-gated channel KCNH2 is a well-known gene in which mutations induce familial QT interval prolongation. KCNH2 is suggested to be a risk gene for schizophrenia.

QT interval has been determined in 103 monozygotic (MZ) and 198 dizygotic (DZ) female twins. Mean values of corrected QT (QTc) were almost identical for both groups at 413 ms (MZ) and 412 ms (DZ). There was a significant age and environmental effect on QT interval. Heritability explained about 25% of the variation in QT.

CLINICAL SIGNIFICANCE OF DRUGINDUCED INTERVALS QT AND QTC PROLONGATION
Interval QT prolongation is a predictor of the life-threatening cardiac arrhythmias — polymorphic ventricular tachycardia (torsade de pointes). Long QT syndrome may be congenital or acquired.
