TL;DR
A case of torsades de pointes that was precipitated by substance abuse in a patient with idiopathic long Q-T syndrome and required several treatment modalities is presented.
Abstract
Torsades de pointes is a ventricular tachycardia characterized by the QRS complexes of changing amplitude that appear to twist around an isoelectric line. It usually precipitates in the setting of underlying Q-T interval prolongation, which has both congenital and acquired causes. The common acquired causes of torsades precipitation are medications, electrolyte imbalance, and severe bradycardia. This report presents a case of torsades de pointes that was precipitated by substance abuse in a patient with idiopathic long Q-T syndrome and required several treatment modalities.

Three deaf-mute children all suffered attacks of fainting, probably Adams-Stokes seizures caused by standstill of the heart, and 3 of the children died in such attacks at the ages of 4, 5, and 9 years, respectively.

The identification of disease genes in LQTS represents a major milestone in understanding the mechanisms underlying this disease but also presents new opportunities for combined research at the molecular, cellular, and clinical levels to understand issues such as adrenergic regulation of cardiac electrophysiology and mechanisms of susceptibility to arrhythmias in L QTS and other settings.

Magnesium can be given safely even in patients with acute myocardial infarction, angina pectoris or systemic hypertension, conditions in which isoproterenol is contraindicated; it can be applied faster than temporary cardiac pacing; and its use for TdP appears worthy of additional trials.

Patients with complete atrioventricular block with TdP had a bradycardia-sensitive repolarization abnormality and this characteristic remained after pacemaker implantation and the QT interval changes in relation to the heart rate were examined.

The development of new agents that potently prolong repolarization will give a modern realization of the old concept that prolongation of refractoriness is a uniquely powerful anti-re-entrant, antitachyarrhythmic action.

Intensive study of the clinical features and basic mechanisms underlying torsade de pointes has led to the definition of a new mechanism for cardiac arrhythmias; understanding such mechanisms may ultimately lead to the development of safer antiarrhythmic therapy.

After spontaneously acquiring complete heart block, two children presented with torsade de pointes as a result of inappropriate prolongation of the QT interval, demonstrating that syncopal episodes, and possibly sudden death, in children with acquired heart block can be due to bradycardia-induced ventricular tachyarrhythmias, rather than extreme bradycardsia per se.
