Corrected QT Interval in Children With Brain Death [PDF]

Pediatric Cardiology, 2010
Prolongation of the QT interval is a well-documented finding in adults with severe brain injury. However, QT prolongation has not been well documented in the pediatric population with brain injury. Our objective was to determine the range of QT intervals

Assessment of Corrected QT Interval and QT Dispersion in Patients with Uncomplicated Metabolic Syndrome.

J Pharm Bioallied Sci, 2023
ABSTRACT Aim: Metabolic syndrome (MS) itself has become a new entity being a constellation of physiological, biochemical, metabolic, and clinical factors that have been related to an increased risk of cardiovascular diseases, type 2 diabetes mellitus (T2DM), and morbidity and mortality.

An Evaluation of P Wave Dispersion, QT, Corrected QT and Corrected QT Dispersion Intervals on the Electrocardiograms of Malnourished Adults [PDF]

Anaesthesia and Intensive Care, 2010
The aim of our study was to investigate P wave dispersion (Pwd), QT, corrected QT (QTc), QT dispersion (QTd) and corrected QT dispersion (QTcd) intervals in subjects with malnutrition diagnosed in the pre-anaesthetic assessment, compared to those without malnutrition. A total of 76 adult patients were included.

Automated versus Manual Measurement of the QT Interval and Corrected QT Interval [PDF]

Annals of Noninvasive Electrocardiology, 2011
Background: The International Conference on Harmonization E14 Guideline specifies detailed assessment of QT interval or corrected QT interval prolongation when developing new drugs. We recently devised new software to precisely measure the QT interval.

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 ...

Changes in the corrected QT interval and corrected QT dispersion during haemodialysis [PDF]

Postgraduate Medical Journal, 2002
Abstract The link between increased QT dispersion and cardiac death in subjects with diabetes and arterial disease is well recognised. Corrected QT dispersion was studied in subjects with end stage renal failure on haemodialysis. Thirty one stable, chronic subjects on haemodialysis had 12-lead electrocardiograms (ECGs) taken before and ...

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 ...

Palbociclib has no clinically relevant effect on the QTc interval in patients with advanced breast cancer. [PDF]

, 2018
The aim of this study was to assess the potential effects of palbociclib in combination with letrozole on QTc. PALOMA-2, a phase 3, randomized, double-blind, placebo-controlled trial, compared palbociclib plus letrozole with placebo plus letrozole in ...

Correction of the QT Interval in Children.

Japanese Circulation Journal, 1995
We evaluated the usefulness of 11 formulas for correcting the QT interval in children, including the square root, cubic root, logarithmic, linear, exponential, and inverse formulas using the Mean-squared residual (MSR) values and Akaike Information Criterion (AIC) in 8,086 first-graders, 9,989 seventh-graders, and 5,786 tenth-graders. The subjects were

Manual vs. automatic assessment of the QT-interval and corrected QT

Europace, 2023
Abstract Aims Sudden cardiac death (SCD) is challenging to predict. Electrocardiogram (ECG)-derived heart rate-corrected QT-interval (QTc) is used for SCD-risk assessment. QTc is preferably determined manually, but vendor-provided automatic results from ECG recorders are convenient.
