If the QT interval lasts longer than 0.50 second (500 milliseconds), then a pa- tient’s heart rhythm is more likely to prog- ress into TdP, an irregular chaotic heartbeat that’s a type of polymorphic ventricular tachycardia (VT). To determine whether a polymorphic VT is TdP, look at the beats around it.

2 Delayed ventricular repolarisation will lead to early after-depolarisations, which can result in re-entrant pathways or focal activity and torsades de pointes ().Many drugs have been implicated in QT prolongation 2018-10-01 First, identification of a prolonged heart rate (HR)-corrected QT interval (QTc) may suggest an inherited propensity to sudden cardiac death (ie, congenital long QT syndrome, a diagnosis of particular concern in patients presenting with syncope) 2 – 4; or it may bring to light an increased susceptibility to development of life-threatening torsade de pointes ventricular tachycardia in An electrocardiographic finding in which the QT interval not corrected for heart rate is prolonged. Thresholds for different age, gender, and patient populations exist. (CDISC) prolonged QT syndrome: Definition Prolonged QT syndrome, also known as long QT syndrome (LQTS), refers to a group of disorders that increase the risk for sudden death due to an abnormal heartbeat. Description Abnormal heartbeats (cardiac arrhythmias ) are a primary cause of sudden death, especially in the young population. In the United Drugs That Prolong the QT Interval and/or Induce Torsades de Pointes Introduction: Prolongation of the QT interval can lead to a life threatening ventricular arrhythmia- torsades de pointes (TdP) - which can result in sudden cardiac death. There are three mechanisms by which drugs can interact and increase the risk of QT prolongation: INTRODUCTION. 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).

Diagnosis. The diagnosis is usually made after you've had a standard EKG that shows a long QT interval. Normally the QT interval is about a third of each heartbeat cycle.

Yes, I have Long QT Syndrome. Yes, my QT interval is long (at times, at least). It could be normal or borderline long or crazy long right this instant. I have no idea because I am not currently getting an EKG. QT interval, and with the presence of other risk factors for this effect.
