ORDER INFORMATION

Why Should We Use Offset ECG Electrodes?

When patients underwent holter ECG detection and telemetric ECG monitor, due to the occurrence of clothing friction, lying gravity, and pulling, it causes artifactual interference[1] in the ECG signal, making it more difficult for physicians to diagnose.
Using offset ECG electrodes can substantially decrease artifact interference and improve the quality of raw ECG signal acquisition, thereby reducing the rate of missed diagnoses of cardiac disease in holter testing and false alarms in telemetric ECG monitoring by clinicians[2].

Product Advantages

Reliable:The offset fitting design, effective buffer pulling area, greatly prevent motion artifacts interference, ensure that the signal is stable and reliable.
Stable:Patented Ag/AgCL printing process, faster through resistance detection, ensure the stability of long-time data transmission.
Comfortable:Overall softness: medical non-woven backing, with soft and breathable, more helpful to sweat evaporation out and improve patient’s comfort level.

Comparison Test: Offset ECG Electrode and Center ECG Electrode

Tapping Test:

Center ECG Electrode Offset ECG Electrode

When the patient lying flat, andconnected to the ECG leadwire,make pressure on the conductive   hydrogel, then there is a change in contact resistance around theconductive hydrogel. When the patient lying flat, andconnected to the ECG leadwire,does not exert pressure on theconductive hydrogel, which haslittle effect on the contact resistance arounding the conductive hydrogel.

Using the simulator separately tap to the connections of the offset ECG electrodes and Center fitting ECG electrodes every 4 seconds, and the  ECGsobtained were as follows:

Results:The ECG signal changedsignificantly, baseline drift up to 7000uV. Results:The ECG signal is unaffected,   continustly to produce reliable ECG data.

Pulling Test

Center ECG Electrode Offset ECG Electrode
 20  21
When the ECG leadwire is pulled, the force Fa1 acts on the skin-gelinterface and the AgCLelectrode-gel interface, when the    AgCL sensor and the conductive    hydrogel are displaced by the pull, both interfere with electricalcontact with the skin, then produc ECG signal artifacts. When pulling the ECG leadwire, the force Fa2 acts at theskin-adhesive gel interface, does not dissipate in the conductive    hydrogel region, so it producefewer artifacts are produced.
In the direction perpendicular to the skin sensor plane, with a force ofF=1N, the ECG leadwire on the center electrode and eccentric electrode were pulled separately about every 3 seconds, and the ECGs obtained    were as follows:23
The ECG signals produced by the two electrodes was looked exactly same before the lead wires pulled.
Results:After the second pull of the ECGleadwire, the ECG signal showedimmediately baseline drift up to7000uV. The potential baseline drift up to ±1000uV and boes not fullyrecover signal instability. Results:After the second pull of the ECGleadwire, the ECG signal showed   temporary drop 1000uV, but the    signal recovered rapidly within 0.1 seconds.
