Two children with extensively drug-resistant tuberculosis were put on bedaquiline and delamanid and had prolonged QTc on the Bazett formula but normal QTc by the Fridericia formula. Both had no adverse effects. Correct formula for monitoring QTc should be used thereby preventing unnecessary withholding...

ECG showed sinus rhythm with first-degree atrioventricular (AV) block, ventricular rate of 80bpm, QTc 456ms, QRS 121ms, PR interval 306ms, and left axis deviation/ hypertrophy. Carotid Doppler ultrasonography also showed 0.7cm by 0.1cm non-stenotic plaque on the right common carotid. There ...
used to treat HIV-1 (Human Immunodeficiency Virus type 1) infection in adults, and in children who are 3 months of age and older and weigh at least 11 pounds (5 kg). A complete treatment regimen of REYATAZ in combination with other antiretroviral medicines is important to properly treat ...
Perioperative Torsade de Pointes (TdP) is a potentially fatal arrhythmia. The association between the prolongation of corrected QT (QTc) interval and TdP has been well described, but prolonged QTc interval is likely not to be a sole determinant. The transmural dispersion of repolarization (TDR) ...
He developed palpitations and weakness 45 minutes after receiving ziprasidone. His QT interval was prolonged on ECG and returned to baseline after 72 hours. They concluded that performing an ECG before ziprasidone dosing should be considered.Sanaei-Zadeh,H.The American journal of emergency medicine...
