UNLABELLED We reviewed 24-h electrocardiographic recordings from 214 genotyped subjects--97 with long-QT syndrome type 1 (LQT1), 62 with LQT2, and 55 unaffected--to record maximal diurnal amplitude ratios between late and early T-wave peaks. Maximal amplitude ratios between late and early T-wave peaks were higher in symptomatic than in asymptomatic patients both in LQT1 (3.2 +/- 1.0 vs. 2.3 +/-...
AIMS We studied whether variants previously associated with congenital long QT syndrome (cLQTS) have an effect on the QTc interval in a Danish population sample. Furthermore, we assessed whether carriers of variants in cLQTS-associated genes are more prone to experience syncope compared with non-carriers and whether carriers have an increased mortality compared with non-carriers. METHODS AND ...
T o those of us who were practicing cardiology in the early 1960s, the reports from Jervell and Lange-Nielsen,1 Romano and colleagues,2 and Ward3 were welcome enlightenment for a few of our patients with alarming episodes of syncope and a family history of sudden death. Although Ward reported that one of his original patients responded to ,8-blockade and that form of therapy remains central to ...
The syndrome of long QT interval frequently follows to syncope or a sudden cardiac death on the basis of originated polymorphic ventricular tachycardia of the "torsade de pointes" type. The prolongation of the QT interval in the hereditary form is based on mutation of the genes responsible for the formation of sodium and potassium channels. The authors analyze the occurrence, clinical findings,...
A case is reported of electrocardiographic QT prolongation that was presumbty familial in origin. Torsades de points developed in association with the use ofdothinepin, despite the pmscription of a low dose of this drug.
OBJECTIVES This study was designed to investigate the clinical course of women with long QT syndrome (LQTS) throughout their potential childbearing years. BACKGROUND Only limited data exist regarding the risks associated with pregnancy in women with LQTS. METHODS The risk of experiencing an adverse cardiac event, including syncope, aborted cardiac arrest, and sudden death, during and after ...
The long QT syndrome (LQTS) is a rare, congenital or acquired disease, which may lead to fatal cardiac arrhythmias (torsade de pointes, TdP). In all LQTS subtypes, TdPs are caused by disturbances in cardiac ion channels. Diagnosis is made using clinical, anamnestic and electrocardiographic data. Triggers of TdPs are numerous and should be avoided perioperatively. Sufficient sedation and preoper...
