The ST algorithm has been tested for accuracy of the ST segment data. The significance of the ST
segment changes need to be determined by a clinician.

NOTE
ST analysis is always performed using a dedicated filter which ensures diagnostic quality. ST segment
of the ECG waveform may appear differently from the ST segment of the ST complex. An ECG report is
not of diagnostic quality. Therefore, the ST segment of the ECG waveform on the report may appear
differently from the ST segment of the ST complex. The only report of ECG diagnostic quality is a Rest
ECG report.
NOTE
When monitoring in dual-lead mode, ECG signal processing uses pre-determined logic to assess signal
quality and determine which lead to use for analysis. If the first lead's signal quality is poor but the second
lead's signal quality is good, the algorithm puts more weight on the good lead for monitoring the patient's
condition.
