The arrhythmia and ST analysis software extension has the capability to measure ST segment deviations and generate arrhythmia alerts for common ventricle arrhythmia conditions. The arrhythmia and ST alerts can also have user specified alarm levels. Automatic or user adjustable ST measurement points are provided. The monitor measures ST segments continuously from the real-time waveform collected by the internal ECG module. ST elevations are reported on-screen as current numerical values, as short term graphs and long term trends. The arrhythmia and ST analysis is fully integrated with the standard ECG package of the monitor. The standard ECG alarms and ECG lead switching is available when using this feature.

This software package is intended for use by physicians to assist with the detection of ventricular arrhythmias and deviations in ST segment elevations that may indicate the presence of myocardial ischemia. The monitor provides detection of only specific conditions within a defined range of physiological parameters as stated in these instructions. The physician is responsible for the interpretation of the monitored data and alerts that are made available.
