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

A system for determining the Q and J points of an electrocardiogram (ECG) combines a WLT-based Q, J detection algorithm with signal quality assessment for lead selection. A Q, J detector () receives a beat-cycle waveform for the beat under consideration from each of a plurality (N) of ECG leads, and assesses signal quality for each lead using signal quality assessor (SQA) components. The leads with 'good' signal qualities are employed for a multichannel waveform length transform (WLT), which yields a combined waveform length signal (CWLS). The Q and J points are then determined from the CWLS.
