3.2 ECG Measurement
3.2.1 ECG Measuring Method
Chest Measurement
In order to obtain ideal ECG waveform, chest
measurement is suggested firstly. Hold the device with
the right hand. Make sure that the palm and fingers
touch the metal electrode I and II reliably.
Place the electrode III on bare skin about 5cm away
below the left nipple. The ECG signal detected by Chest
Measurement is similar to Lead V ECG signal.
Improper operating method:
A. The contact place of electrode III deviates from left
chest.
B. The holding gesture is incorrect.
C. The electrode can not contact bare skin completely.
(For example place the electrode on clothing.)
Leg Measurement
If it is not convenient to use chest measurement,
the leg measurement will be recommended. When
measuring, hold the device with the right hand.
Make sure that the palm and fingers touch the metal
electrode I and II reliably. Place the electrode III on
the skin 10cm away above the left foot ankle. The
ECG signal detected by Leg Measurement is
equivalent to Lead II ECG signal.
Improper operating method:
A. Wrong holding gesture.
B. The electrode III can not contact bare skin
completely. (For example, place the electrode III on
the sleeve of trousers or socks.)
Palm Measurement
Hold the device with right hand. Make sure that the palm
and fingers touch the metal electrode I and II reliably.
Press the electrode III close against the center of the
left palm. The ECG signal detected by Palm
Measurement is equivalent to Lead I ECG signal.
Improper operating method:
A. Waving your both hands at will.
B. Both hands loose contact with electrodes during
measurement.
C. Not palm contacts the electrode.
