  • QT interval monitoring system with alarms and trending
    Patent number: 9538933
    Abstract: An ECG monitoring system continuously monitors a patient's ECG waveform and periodically identifies the patient's QT interval. QT interval values are averaged over time and a corrected interval value QTc and a change in QTc relative to a baseline, dQTc, are periodically produced. An alarm is responsive to updated QT interval values and issues an alarm whenever a selected QT value exceeds an alarm limit. The periodically produced QT interval values are stored and a trend display may be produced showing changes in the QT interval information over different periods of time. The trend display may selectively display the trend information either graphically or in tabular form.
