Novel genes for QTc interval. How much heritability is explained, and how much is left to find? [PDF]

, 2010
The corrected QT (QTc) interval is a complex quantitative trait, believed to be influenced by several genetic and environmental factors. It is a strong prognostic indicator of cardiovascular mortality in patients with and without cardiac disease.

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.

Torsades de pointes during laparoscopic adrenalectomy of a pheochromocytoma: a case report

Journal of Medical Case Reports, 2011
Introduction Torsades de pointes is a rare but potentially lethal arrhythmia. The amount of literature available on Torsades de pointes occurring in patients with pheochromocytoma is limited, and we found no literature describing this dysrhythmia in a ...

Defying the Odds of Sudden Cardiac Death in Hypertrophic Cardiomyopathy

JACC: 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 ...

Prolonged QT Interval in Cirrhosis: Twisting Time?

Gut 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).

Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

Advanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

QT interval prolongation in Takotsubo syndrome: a frightening feature with no major prognostic impact

Monaldi Archives for Chest Disease, 2023
Despite the frequent and often severe repolarization abnormalities seen in Takotsubo syndrome (TTS), the underlying mechanism of life-threatening arrhythmias is incompletely understood, and the risk remains uncertain. TTS is considered a potential cause
