WARNING Ensure these things to minimize false HR, Arrhythmia Analysis and
ST Analysis alarms, and to achieve optimal event detection and analysis:
• ECG cable, lead wires and electrodes are undamaged.
• Patient’s skin is properly prepared.
• Electrodes are placed using standard good practices.
• 5-wire ECG cable is used. A 3-wire cable limits arrhythmia and ST-segment
analyses to a single lead, and ST analysis is disabled when a lead failure
occurs.
• LL electrode is connected. Otherwise, only one ECG lead is available and
arrhythmia and ST-segment analyses are effected.
• Patient monitor and Virtual Monitor display these things:
-HR numeric and ECG waveform
-Non-noisy signal. If signal is noisy, reduce patient movement and increase
distance from other electrical devices.
-Correct patient mode for the patient
• Virtual Monitor ECG 1 and 2 display these things:
-ECG waveform
-Waveform amplitude at least 160 µV, peak-to-peak
-QRS complex amplitude at least twice the P or T wave amplitude
