Fatal arrhythmias: Another reason why doctors remain cautious about chloroquine/hydroxychloroquine for treating COVID-19
Early during the current COVID-19 pandemic, hydroxychloroquine (HCQ) received a significant amount of attention as a potential antiviral treatment, such that it became one of the most commonly prescribed medications for COVID-19 patients. However, not only the effectiveness of HCQ has remained questionable, and mainly based on pre-clinical, and a few small clinical studies, but also HCQ is known to be potentially arrhythmogenic, especially as a result of QT prolongation.
