Overview of HR and ECG Control
Heart Rate Numeric
Orange for current Heart Rate displayed on Monitor
Blue for the target Heart Rate changed by the Dial.

Waveform Picker
Tap on the centre of the dial to show the Waveform Picker
ECGs are organised in categories.
Choose an ECG and press Send to activate
If an ECG has the 12 lead ECG symbol then a 12 lead ECG can be shown on 12 lead capable screens (such as the Zoll X and Corpuls3).
Show/Hide
Tap on this to Show or Hide
the Heart Rate or ECG waveform on the Monitor screen.
Pads On/Off button
Tap this to connect Pads or disconnect Pads
Electrode Connection button
Tap this to toggle between electrodes not connected, 6 leads connected and 12 lead connected.
Advanced Heart Rate Controls and Electrode Placement
Tap on the icon to choose Advanced Heart Rate Controls or Advanced Electrode Placement
Advanced Heart Rate Controls
Control Ectopics, Electrical Interference, Artifact, Stroke Volume Variation and Sinus Arrhythmia
Dial and Waveform Picker
This works in the same way as the usual dial and waveform picker
See Overview of Dials and Numerics
Vital sign display
This shows the current vital signs of Blood Pressure, SpO2 and ETCO2
Ectopics
These control the likelihood of PVC, PJC and PAC ectopics as shown in the ECG trace.
These can range from 0 (no ectopics) to 5 (frequent ectopics).
Perfusion
This toggle controls whether on not an ectopic results in a normal perfused pulsatile SpO2 waveform or a poor perfused pulsatile SpO2 waveform.
Normal Perfusion Poor Perfusion
Interference
Both Electrical Interference and Artifact ECG traces can be added to any ECG.
Electrical
Artifact
Artifact can be controlled on a 0 to 5 scale.
The image below shows increasing levels of artifact in a single trace.
Stroke Volume Variation (SVV)
This can be controlled from 0 to 50% SVV.
With increasing SVV, the invasive arterial waveform demonstrates more 'swing'.
If the Vent toggle is used, the swing will be consistent with a patient who is positively pressure ventilated.
Note: the Respiratory Rate must be set to a value greater than zero to activate this.
In the image below, the Heart Rate=100 and the Respiratory Rate=20
Sinus Arrhythmia (SA)
This controls the amount of Sinus Arrhythmia shown on an ECG trace.
It can be controlled from 1x up to 2.5x.
If the Vent toggle is used, the arrhythmia will be consistent with a patient who is positively pressure ventilated.
Note: the Respiratory Rate must be set to a value greater than zero to activate this.
In the image below, the Heart Rate=78 and the Respiratory Rate=20
The upper trace has the SA = 1x
The lower trace has the SA = 1.6x
Electrode Placement and 12 Lead ECG
This is particularly useful when running scenarios with AEDs and Semi-automatic AEDs
With Manual Placement you can select individual electrodes and pads to be active (orange ) or inactive (grey).
Alternatively, select from the Quick Placement options
To send a 12 Lead ECG to the monitor screen or Chart immediately, tap on Send 12 Lead and a static 12 Lead ECG will be shown on the monitor screen.
Note: Some ECG waveforms do not have an associated 12 lead
