Mayo Clinic Creates Institution-Wide Electronic Prolonged QT Interval Warning System

By Logan Lafferty

Using a one-of-a-kind computer-aided program, Mayo Clinic has developed and implemented a Mayo-wide electronic warning system to identify patients at risk of QT-related deaths from an abnormality in the heart's electrical system. The system informs all physicians, regardless of their specialty or QT awareness, if their patient's ECG activated the QT alarm. In addition, the researchers discovered that the death rate of patients whose 12-lead electrocardiogram (ECG) activated the QT alert was nearly four times greater than all other patients who had an ECG. The findings are published in the current issue of Mayo Clinic Proceedings.
