ECG Alarm Alerts Docs to Silent Killer

By Logan Lafferty

An institution-wide, computer-based alert system for irregular heart rhythms identified and characterized patients at risk of death, researchers found. Patients identified by the alert system with a greater than 500 ms corrected interval between the Q and T waves of their ECG cycle had a significantly higher risk of death compared with a QTc interval less than 500 ms (19% versus 5%), reported Michael J. Ackerman, MD, PhD, and colleagues from the Mayo Clinic in Rochester, Minn.
