چکیده
A case of paroxysmal ventricular tachycardia of torsade de pointes variety occurring in a newborn infant is described. A rare problem in the newborn, ventricular tachycardia has been associated with congenital heart disease, electrolyte abnormality, and cardiac tumour. In this case, the association was with myocarditis. The arrhythmia was refractory to treatment, and the infant died.

متن کاملA practical approach to torsade de pointes.
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...
