Antipsychotic drugs: prolonged QTc interval, torsade
de pointes, and sudden death.
de pointes remains a consideration in the use of sotalol, although limited published experience with this agent in pregnant women suggests that it is safe.
Because such dose-dependent changes in the electrical activity of the heart can lead to abnormal heart rhythms, including the potentially fatal Torsade
de Pointes, and in the absence of evidence demonstrating that citalopram at doses higher than 40 mg per day is beneficial in the treatment of depression, the FDA determined that citalopram should no longer be used at doses above 40 mg per day and that it should not be used at all in patients with congenital long QT syndrome.
Thirty minutes later the patient developed an episode of torsade
de pointes (TdP) lasting [greater than or equal to] 7.
de pointes due to noncardiac drugs: most patients have easily identifiable risk factors.

15% patients were having severe hypomagnesaemia and all of these patients have torsade
de pointes as the presenting arrhythmia suggesting that severe hypomagnesaemia is an important cause of torsade
c] interval in patients but the torsade
genecity is associated with transmural dispersion of depolarization (TDP), and torsade
only occurs when TDP increases (4).
Electrocardiography abnormalities such as atrial flutter, atrioventricular block, torsade
de pointes, sinus tachycardia, QT prolongation, ST elevation, and T wave inversion were detected in seven patients.
