Altered circadian rhythmicity of the QT interval predicts mortality in a large real-world academic hospital population

Heliyon
Objective and rationale: Small studies have shown that the QT interval follows a circadian rhythm. This finding has never been confirmed in a large real-world hospital population and the clinical meaning of disrupted rhythmicity remains unknown. Methods:

Effects of Neostigmine and Sugammadex for Reversal of Neuromuscular Blockade on QT Dispersion Under Propofol Anesthesia: A Randomized Controlled Trial

Cardiology and Therapy, 2018
Introduction Reversal of non-depolarizing neuromuscular blocking agent neostigmine is associated with QT prolongation under general anesthesia. To clarify the effects of neostigmine and sugammadex on hemodynamic status, the QT interval and QT dispersion ...

Multifactorial QT interval prolongation

, 2010
Acquired long QT interval has been widely reported to be a consequence of drug therapy and electrolyte disturbances. We describe two cases of multifactorial acquired QT interval prolongation and torsades de pointes.

QT Interval Correction in Patients with Cirrhosis

, 2007
Introduction: QT interval prolongation is a common electrophysiological abnormality in patients with cirrhosis. As QT interval varies with the heart rate, many QT correction formulas have been proposed, the Bazett's one being the most criticized because ...

Long QT interval in resting electrocardiogram– and what next? Sports cardiologist’s point ofview Part 2. From provocative tests to prevention of cardiac events

, 2014
Resting electrocardiogram is a basic diagnostic tool used to identify myocardial diseases caused by a genetic defect of ion channels that results in bioelectric instability of cardiomyocytes and the risk of a complex induction of life-threatening ...

Long QT interval in resting electrocardiogram – and what next? Sports cardiologist’s pointofview. Part 1. From electrophysiology to diagnostics

, 2014
Electrocardiography is the most common and available cardiovascular diagnostic procedure and an important tool in everyday clinical practice of a family physician. Electrocardiogram interpretation is therefore an invaluable clinical skill.

Course and prognostic implications of QT interval and QT interval variability after primary coronary angioplasty in acute myocardial infarction

, 2001
OBJECTIVESThe aim of this study was to determine the influence of early reperfusion on the course of QT interval and QT interval variability in patients undergoing primary percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial ...

Cardiovascular regulation and vascular structure in prehypertension and coronary heart disease

, 2009
The aim of this thesis was to characterize vascular structure and different aspects of cardiovascular regulation in otherwise healthy subjects with slightly elevated blood pressure and compare to healthy subjects with normotension and also investigate ...

QT interval abnormalities: Risk factors and perioperative management in long QT syndromes and Torsades de Pointes

, 2013
Electrophysiological abnormalities of the QT interval of the standard electrocardiogram are not uncommon. Congenital long QT syndrome is due to mutations of several possible genes (genotype) that result in prolongation of the corrected QT interval ...
