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.

A Remarkable Point: QT Dispersion in Trained Athletes

Haseki Tıp Bülteni, 2010
Aim: It is a common belief that QT dispersion can increase the risk of cardiac death by inducing arrhythmias and that this is a consequence of changes in the ventricular muscles due to heavy training.

The causes and significance of QT dispersion after myocardial infarction.

, 1996
QT dispersion is an easily obtained measurement from the standard electrocardiogram, and is the maximum minus the minimum QT interval. QT dispersion might represent dispersion of ventricular repolarisation, and be a marker of arrhythmic substrates.

Increased vulnerability of human ventricle to re-entrant excitation in hERG-linked variant 1 short QT syndrome [PDF]

, 2011
The short QT syndrome (SQTS) is a genetically heterogeneous condition characterized by abbreviated QT intervals and an increased susceptibility to arrhythmia and sudden death.

QT Dispersion Increases with Aging [PDF]

Annals of Noninvasive Electrocardiology, 2006
Background:Age‐related changes in cardiovascular system are well‐known. Arrhythmias in elderly patients constitute most of the urgencies, consultations, or hospitalizations. QT dispersion (QTd) is a simple noninvasive arrhythmogenic marker to demonstrate the electrical instability of the heart.

The Effects of Local Anaesthetics on QT Parameters during Thoracic Epidural Anaesthesia Combined with General Anaesthesia: Ropivacaine versus Bupivacaine

Balkan Medical Journal, 2013
Background: Many studies focusing on the effects of local anaesthetics on QT intervals have been performed, but the articles evaluating the relationship between thoracic epidural anaesthesia combined with general anaesthesia and QT parameters are very ...

Relationship between QT interval and ventricular electrical axis: A new suggestion for Lead selection in QT interval measurement [PDF]

Acta Medica Iranica, 2000
Exploration of the interlead QT variation (QT dispersion) introduced cardiologists to some new concepts including the deed to define a standard for lead selection in the measurement of QT interval and the reason or factors contributing to QT dispersion ...

Can indicators of myocardial damage predict carbon monoxide poisoning outcomes?

BMC Emergency Medicine, 2021
Background Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient’s prognosis after carbon monoxide poisoning.

Correlation of corrected QT dispersion with the severity of coronary artery disease detected by SYNTAX score in non-diabetic patients with STEMI

The Egyptian Heart Journal, 2017
Introduction: Determination of the QT interval dispersion by means of a standard ECG at rest has been widely used for cardiovascular risk assessment during the last 15 years as one of the recent explanations for the development of life threatening ...

The Impact of Positive and Negative Affect on QT Dispersion in Healthy Young Adult Men

Psychiatry and Clinical Psychopharmacology, 2021
Objective: In this study, we aimed to determine whether QT dispersion known to be associated with development of coronary artery disease is related with positive (PA) and negative affect (NA) in healthy young adult men.
