6.1.11 ECG Relearn

Manually Starting ECG Relearn
During ECG monitoring, you may need to start ECG relearn when the patient‘s ECG templates undergo
significant changes. Changes of ECG templates may lead to:

Wrong arrhythmia alarm

ST measurement loss

Incorrect heart rate
ECG relearn function enables the monitor to learn new ECG templates for correcting arrhythmia alarm and
recovering ST measurement. To manually start ECG relearn: select [Main Menu]-[Parameters]-[ECG
Setup]-[Relearn], or select ECG Waveform Region or Parameter Region, then [ECG Setup]-[Relearn].
Attention

Please start the relearn function during normal rhythm or when ECG signals are relatively absent of
noise. Because if you start ECG relearn during arrhythmia, the wrong QRS waves may be learned
as ECG templates leading to missed detection of arrhythmia events.

Auto-Starting ECG Relearn
In the following cases, ECG relearn will be automatically started:

Change of animal category.

Change of pacemaking status.

Change of [ECG 1] or [ECG 2] in the [ECG Setup] interface.

To reconnect the cables.
6.2 Resp
6.2.1 Resp General Description
This series of monitors‘ measure respiration through the method of thoracic electrical bio impedance. The size and
shape of a breathing animal‘s thoracic cavity varies, resulting in changes in impedance between the two electrodes
placed on the animal‘s chest. Thus the breathing rate can be calculated according to the impedance variation
cycles.
Warning

Anti-electrotome ECG cables are prohibited for use while monitoring an animal
’s respiration.

All leads on 5-lead ECG cables should be connected with an animal
’s body for the sake of safety.

Respiration measure is unable to find the causes of apnea, thus it cannot be used for diagnostic
purpose.
