Transient Long QT Development in a Patient with Takotsubo Cardiomyopathy

open access: yesJournal of Cardiovascular Emergencies, 2016
QT interval prolongation on the electrocardiogram is considered a precursory sign for imminent, potentially lethal ventricular arrhythmias. Beside the inherited condition of long QT syndrome, numerous drugs, certain electrolyte disturbances and early ...

Abnormal ECG Findings in Athletes: Clinical Evaluation and Considerations. [PDF]

open access: yes, 2019
PURPOSE OF REVIEW: Pre-participation cardiovascular evaluation with electrocardiography is normal practice for most sporting bodies. Awareness about sudden cardiac death in athletes and recognizing how screening can help identify vulnerable athletes have

R-from-T as a common mechanism of arrhythmia initiation in long QT syndromes [PDF]

open access: yes, 2019
Background: Long QT syndromes (LQTS) arise from many genetic and nongenetic causes with certain characteristic ECG features preceding polymorphic ventricular tachyarrhythmias (PVTs).

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.

Prevalence of Long QT Syndrome in Children with Congenital Sensory-Neural Deafness

open access: yesJournal of Ardabil University of Medical Sciences, 2021
Background & objectives: Long QT syndrome (LQTS), congenital or acquired disorder, is characterized by a prolonged QT interval associated with syncope attacks and sudden death.

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

open access: yesPediatria i Medycyna Rodzinna, 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.

Defying the Odds of Sudden Cardiac Death in Hypertrophic Cardiomyopathy

open access: yesJACC: Case Reports, 2020
We report an unusual case of a patient with hypertrophic obstructive cardiomyopathy, anomalous aortic origin of a coronary artery, obesity hypoventilation syndrome, and acquired long QT syndrome who was able to defy the odds of sudden cardiac death in ...

The role of M cells and the long QT syndrome in cardiac arrhythmias: simulation studies of reentrant excitations using a detailed electrophysiological model

open access: yes, 2004
In this numerical study, we investigate the role of intrinsic heterogeneities of cardiac tissue due to M cells in the generation and maintenance of reentrant excitations using the detailed Luo-Rudy dynamic model. This model has been extended to include a

Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

open access: yes, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular

Prolonged QT Interval in Cirrhosis: Twisting Time?

open access: yesGut and Liver, 2022
Approximately 30% to 70% of patients with cirrhosis have QT interval prolongation. In patients without cirrhosis, QT prolongation is associated with an increased risk of ventricular arrhythmias, such as torsade de pointes (TdP).
