Cost Reduction Initiatives in QT Monitoring
A substantial number of medications have been described to prolong the QT interval, which can predispose patients to potentially fatal ventricular arrhythmias. When patients are prescribed medications known to prolong the QT interval, a 12-lead ECG is often ordered at baseline and at regular intervals to monitor for QT prolongation. The resultant patient charge per 12-lead ECG for recording and interpretation by a cardiologist is approximately $500.
