QT prolongation is a condition characterized by a lengthened QT interval on an electrocardiogram (ECG), which represents the time it takes for the heart to repolarize after a heartbeat. This can lead to an increased risk of arrhythmias, specifically a type of arrhythmia known as Torsades de Pointes, which can be life-threatening. Research in this area focuses on understanding the causes of QT prolongation, identifying individuals at risk, and developing treatments and interventions to prevent adverse outcomes associated with this condition. This research is critical in improving the diagnosis, management, and outcomes of individuals with QT prolongation.
