Prolonged QT Interval: A Tricky Diagnosis? [PDF]

The American Journal of Cardiology, 1997
Prolonged heart-rate adjusted QT intervals on the electrocardiogram (ECG) are associated with an increased risk for coronary heart disease and sudden death. However, the diagnosis of the prolonged QT interval is hampered by lack of standards. We studied variations in the prevalence of prolonged QT, based on different common definitions, in a large ...

First‐Line Osimertinib in Patients with EGFR‐Mutant Advanced Non‐Small Cell Lung Cancer: Outcome and Safety in the Real World: FLOWER Study

The Oncologist, EarlyView., 2021
Abstract Lessons Learned Osimertinib has confirmed effectiveness in this real‐world population of patients with EGFR‐mutant advanced non‐small cell lung cancer. Thromboembolic events occur more frequently than previously reported, suggesting a thrombotic diathesis that requires further investigation. Patients with at least three metastatic sites, brain

A Twist on Torsade: A Prolonged QT Interval on Methadone [PDF]

Journal of General Internal Medicine, 2006
A woman developed a prolonged QT interval and torsade de pointes while on methadone treatment for heroin addiction. We think methadone, or its impaired metabolism, was the major cause for her prolonged QT interval and progression to torsade. However, torsade is often multifactorial, as was likely so in this case.
