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.

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.

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.

Short-Term Beat-to-Beat QT Variability Appears Influenced More Strongly by Recording Quality Than by Beat-to-Beat RR Variability

Frontiers in Physiology, 2022
Increases in beat-to-beat variability of electrocardiographic QT interval duration have repeatedly been associated with increased risk of cardiovascular events and complications.

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

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 ...

Increased Short-Term Beat-To-Beat Variability of QT Interval in Patients with Acromegaly. [PDF]

, 2015
Cardiovascular diseases, including ventricular arrhythmias are responsible for increased mortality in patients with acromegaly. Acromegaly may cause repolarization abnormalities such as QT prolongation and impairment of repolarization reserve enhancing ...

QT interval analysis in type 2 diabetic patients

مجلة كلية الطب, 2011
Background: The electrocardiographic QT interval has been extensively studied in diabetes mellitus. Recently, there has been increasing interest in the relationship between diabetes and QT abnormalities .The QT interval, which is easily obtained from a ...

QTc evaluation in patients with bundle branch block

International Journal of Cardiology: Heart & Vasculature, 2020
Proper measurement of the QT interval on the 12-lead body-surface ECG is challenging in daily practice. Even more difficult is its correct estimation in the presence of repolarization abnormalities, arrhythmias or bundle-branch blocks (BBB).

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

Acta 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 ...

A genome-wide association scan of RR and QT interval duration in 3 European genetically isolated populations:the EUROSPAN project [PDF]

, 2009
We set out to identify common genetic determinants of the length of the RR and QT intervals in 2325 individuals from isolated European populations.We analyzed the heart rate at rest, measured as the RR interval, and the length of the corrected QT ...
