Långt QT-syndrom - Medibas

Torsades de pointes (TdP), a potentially fatal polymorphic ventricular tachyarrhythmia , often occurs in association with a prolonged QT interval or a heart-rate–corrected QT interval (QTc), and it may present as sudden death, syncope (originally described as “quinidine syncope” in the 1920s), dizziness, palpitations, seizures, ventricular tachycardia, or not at all (asymptomatic) if the the QT interval is prolonged. This places the patient at risk for a life-threatening arrhythmia of ventricular tachycardia (Torsades de Pointes). This finding may need treatment in order to avoid this arrhythmia and potentially sudden death. 2021-03-20 · Corrected QT. See also: Corrected QT calculator The QT interval varies depending on hear rate, it decreases at faster heart rates and it lengthens at slower rates, so to determine whether is normal or not it should undergo adequate rate correction (corrected QT or QTc). The long QT syndrome (LQTS) is a disorder of myocardial repolarization characterized by a prolonged QT interval on the electrocardiogram (ECG) . This syndrome is associated with an increased risk of polymorphic ventricular tachycardia, a characteristic life-threatening cardiac arrhythmia also known as torsades de pointes ( waveform 2A-B ).

The QT interval is the time interval from the beginning of the QRS complex to the end of the T-wave. This interval represents the total time taken to de- and repolarize the ventricles (Figure 1). For example, in the Rotterdam QT Project the association between prolonged QTc interval and sudden death was not significant in the subgroup of patients with left ventricular dysfunction.

Abnormally prolonged QTc interval is referred to as long QTc interval (or just long QT interval, without the “c”). The upper reference limit for QTc interval is 460 ms in males and 470 ms in females.
