Control - Section 2: Heart Rate and ECG Control

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.

 

Numeric Dial

Changes the Heart Rate value
See Overview of Dials and Numerics

 

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
