Effect of QT interval-prolonging drugs taken in pregnancy on the neonatal QT interval
Frontiers in Pharmacology, 2023 Introduction: Acquired QT interval prolongations due to drug side effects can result in detrimental arrhythmia. Maternal use of placenta-permeable drugs may lead to fetal exposure, thus leading to an increased risk of neonatal QT prolongation and ...

A Study on the Diurnal Variation of Ventricular Repolarization Parameters in Patients with Obstructive Sleep Apnea [PDF]
Zhongguo quanke yixue, 2022 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.

The Measurement of the QT Interval [PDF]
Current Cardiology Reviews, 2014 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
The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2021 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.

CLINICAL SIGNIFICANCE OF DRUGINDUCED INTERVALS QT AND QTC PROLONGATION
Рациональная фармакотерапия в кардиологии, 2015 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.

Journal of Human Hypertension, 2000 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.

QT is longer in drug-free patients with schizophrenia compared with age-matched healthy subjects. [PDF]
PLoS ONE, 2014 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.

Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2019 Interpretation of each electrocardiogram should include measurement and evaluation of the QT interval, because both an increase and a decrease in its duration are associated with a risk of polymorphic ventricular tachycardia and sudden cardiac death ...
