Prolongation of the QT interval can lead to a life threatening ventricular arrhythmia known as torsades de pointes which can result in sudden cardiac death. The risk of torsades de pointes depends on patient factors and current medication. Purpose of Review The objective of this manuscript is to describe the cardiovascular effects of the gabapentinoids gabapentin and pregabalin. Recent Findings The most frequent adverse effects of gabapentin and pregabalin affect the central nervous system, such as somnolence and fatigue. Additionally, pregabalin, and a much lesser extent, gabapentin, may adversely affect the cardiovascular The most commonly reported adverse events with gabapentin enacarbil 6000 mg were dizziness and somnolence (60.0% and 54.0%, respectively). Conclusion: In this population of healthy adults, gabapentin enacarbil at doses of 1200 and 6000 mg was not associated with QT prolongation and was generally well-tolerated. In particular, the potential for these medications, either alone or in combination, to prolong the QT interval should be considered. This review will discuss mechanisms for drug-induced QT prolongation and its relationship to potentially fatal arrhythmias such as torsades de pointes. Long QT syndrome (LQTS) is a cardiac conduction disorder characterized by prolongation and increased dispersion of ventricular repolarization, manifested by lengthening of the QT interval on the surface electrocardiography (ECG). Drugs associated with QT Prolongation, QTc prolongation including Antipsychotics, antiarrhythmics, antidepressants, and antihistamines nels, including long QT, are described for tramadol [18]. A recent study in 115 patients showed a clear positive corre-lation between plasma tramadol concentration and QT du-ration [19]. Buprenorphine was traditionally considered to be a rel-atively safe drug in regards to developing long QT syn-drome [20,21]. However, recent reports indicate induced QT prolongation and drug . interactions Prolongation of the QT interval can lead to a life threatening ventricular arrhythmia known as torsades de pointes which can result in sudden cardiac death. There are a number of widely used drugs which are known to cause QT prolongation.

Electrocardiogram qt corrected interval prolonged is reported as a side effect among people who take Gabapentin (gabapentin), especially for people who are female, 40-49 old, also take Mirtazapine, and have High blood pressure. Long QT syndrome is a cardiac repolarization disorder, and is associated with an increased risk of torsades de pointes (TdP), a life-threatening type of polymorphic ventricular tachycardia, and sudden cardiac death [1]. Acquired and congenital forms can be distinguished. Among the mood stabilizers, lithium has a moderate risk of QTc prolongation while the antiepileptics used for this purpose such as carbamazepine, oxcarbazepine, topiramate, valproate, pregabalin, gabapentin, and lamotrigine are reported to be safe with a low risk of QTc prolongation. My Long QT interval was 530 for a week in hospital whilst I was hypokalaemic and taking citalopram for anxiety. It has since reverted to normal because I was taken off all meds immediately except a statin and thyroxine. A comprehensive list of conditions and drugs that may prolong the QT interval, and cause torsade de pointes (TdP) and long QT syndrome (LQTS) is presented below. With regards to drugs, the risk of QT prolongation and TdP varies markedly across the list but tends to be rather similar within a drug class. Many drug therapies are associated with prolongation of the QT interval. This may increase the risk of Torsades de Pointes (TdP), a potentially life-threatening cardiac arrhythmia. As the QT interval varies with a change in heart rate, various formulae can adjust for this, producing a 'corrected QT' (QTc) value. Slow heart rate prolongs the repolarization phase, making an individual vulnerable to drug-induced prolongation of the QT interval. Heart failure has been associated with extended action potentials by blocked IKr channels, leading to an increased risk of drug-induced arrhythmias. Many drugs are notoriously known to prolong the QT interval, especially those used in cardiology and psychiatry practice. QT prolongation can remain asymptomatic or lead to torsades de pointes (TdP), a rare tachyarrhythmia which can be life-threatening or nearly fatal due to ventricular fibrillation and sudden cardiac death. QT interval varies dependent on the length of the cardiac cycle and is usually corrected (QTc) for heart rate, several formulas can be used for this, most commonly Bazett’s formula is used (QTc=QT/√RR; QT interval in seconds, RR cardiac cycle in seconds), other correction formulae such as Frederica, Hodges or Framingham may be used.
