A, Normal sinus rhythm; the Bazett formula is used to correct the QT interval for the heart rate. B, Atrial fibrillation; QT interval is calculated by taking the average of QT intervals with shortest and longest preceding R-R intervals. Pharmacokinetic Interactions With Selected QT-Prolonging ...
How to measure the QT interval--what is normal? The QT interval extends from the beginning of the QRS complex to the end of the T wave. Since the report of Jervell and Lange-Nielsen in 1957, it has been difficult to determine whether to measure a QT or a QU interval. U waves are ...
Hydroxychloroquine’s possible effects on the QT interval is not a major issue. Azithromycin is one of the most frequently prescribed antibiotics. That drug is known to potentially prolong the QT interval which can be related to heart arrhythmias. So one should probably check an EKG to make sure...

Cardiac arrest due to torsades de pointes (TdP) is an uncommon but potentially catastrophic event associated with QT interval-prolonging drugs [ 1 ]. Numerous medications that may cause TdP are available for use in clinical practice, and include drugs for management of cardiovascular diseases, prima...
The first thing to know about ECGs is the waveforms. There is a P wave, the PR interval, and the QT interval which contains the QRS complex, the ST segment, and the T wave. There are a lot of variables to take into consideration when reading an ECG like current medications and ...
