A medical display system () and method display physiological signals. A physiological signal of a patient () is received, the physiological signal spanning a period of time. Signal quality of the physiological signal over the period of time is determined. An ECG signal () is displayed using a compressed time scale and the determined signal quality ()over time is displayed adjacent to the displayed physiological signal.

Method and display for long term physiological signal quality indication

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.
