The term torsade de pointes refers to polymorphic ventricular tachycardia that occurs in the setting of an abnormally long QT interval. While the most common cause is treatment with QT prolonging drugs, torsade de pointes also occurs in the congenital long QT syndromes and in the setting of acquired heart block or severe electrolyte disturbance, notably hypokalemia. Among QT prolonging drugs th...
INTRODUCTION Torsades de pointes is a rare but potentially lethal arrhythmia. The amount of literature available on Torsades de pointes occurring in patients with pheochromocytoma is limited, and we found no literature describing this dysrhythmia in a patient with pheochromocytoma under anesthesia. CASE PRESENTATION We describe the case of a 42-year-old Caucasian woman without QT prolongation...
BACKGROUND Competitive sports participation for athletes with congenital long QT syndrome (LQTS) is guided by the 2005 36th Bethesda Conference and the 2005 European Society of Cardiology (ESC) guidelines. The purpose of this study was to determine the prevalence and outcomes of patients with LQTS who chose to remain athletes following their diagnosis. METHODS Records of all patients between ...
BACKGROUND Congenital long-QT syndrome (LQTS) is caused by mutations of genes encoding the slow component of the delayed rectifier current (LQT1, LQT5), the rapid component of the delayed rectifier current (LQT2, LQT6), or the Na(+) current (LQT3), resulting in ST-T-wave abnormalities on the ECG. This study evaluated the spectrum of ST-T-wave patterns and repolarization parameters by genotype a...
A 7-year-old boy presented at our hospital with syncope. At birth, electrocardiography had shown a long QT interval with torsade de pointes (TdP). Congenital long QT syndrome (LQTS) had been diagnosed by genetic testing, and was successfully controlled with oral propranolol. At age 7, TdP had recurred with syncope. Electrocardiography revealed a prominent long QT interval with T-wave alternans....
For half a century, the relationship between the QT interval and cardiac arrhythmias has been recognized,1 although attention has focused primarily on prolongation of the QT. The congenital long-QT syndrome (LQTS) was first identified in patients with syncope, aborted sudden death, or family history of cardiac arrest as an association between a prolonged QT interval and development of potential...
