Serial electrocardiogram recordings revealed a high prevalence of QT interval prolongation in patients with tuberculosis receiving fluoroquinolones

open access: yesJournal of the Formosan Medical Association, 2023
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

Corrected QT interval and QT dispersion in temporal lobe epilepsy

open access: yesThe 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

open access: yesРациональная 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.

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

open access: yesPLoS 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.

METHODOLOGICAL APPROACHES TO MEASURING AND ESTIMATING THE DURATION OF QT INTERVAL OF A STANDARD ELECTROCARDIOGRAM

open access: yesŽurnal 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 ...

Increases of QT dispersion, corrected QT dispersion and QT interval in young healthy individuals during Ramadan fasting [PDF]

open access: yesActa Medica Iranica, 2003
Ramadan fasting is one of the most important religious duties of Muslims, that its effect on the heart has not been determined yet. Our objective was to evaluate the effect of Ramadan fasting on ventricular repolarization as assessed by QT interval ...
