The device will confirm all electrodes have contact with the patient’s
skin by the lead indicator icon turning green simultaneously as it
detects skin contact. If the lead indicator is gray, there is not sucient
skin contact.
Note that device display is not recommended to determine the
absolute amplitude of the ECG signal. We recommend that the
display be primarily used for ensuring good ECG signal quality. The
accompanying mobile app should be used to read and interpret the
three lead ECG.
Placement
CORE 500™ streams a 3-lead ECG. Best placement can vary. ECG
electrodes must be placed on the skin. CORE 500™ can also be used to
auscultate at all anatomical positions.
The dots below indicate generally accepted CORE 500™ placement
positions. CORE 500™ is sensitive to vibration and hand movement.
Remember to apply firm and constant pressure against the body to
ensure good contact.
Interpret the ECG
The CORE 500™ displays Channel 1 tracings on the display when
in active skin contact. Channels 1, 2, and 3 will be displayed in the
sequence shown on the Eko App as shown in the figure below. When the
CORE 500 is held vertically, as shown below, the Channels 1, 2, and 3 will
correspond to modified Leads I, II and III, respectively.
