◾ Reduction of interference signals caused by electromagnetic
induction.
– Due to cable loops
– Interferences from electrical potentials caused by muscle
movement
Attach the electrodes so that interferences from electrical
potentials caused by muscle movement and baseline drifts are
minimized. Suitable contact points are therefore areas that show
very little muscle or fatty tissue.
1 Prepare the patient for the examination as early as outside the
examination room.
2 On the chest of the patient, select locations with minimal muscle
and fat tissue for attaching the electrodes.
3 In case of hairy skin: shave the points where you intend to attach
the electrodes.
Shave the patient outside the examination room to prevent
accidents.
4 Thoroughly clean the patient's skin at the locations involved.
However, do not use solutions containing alcohol.
5 Then dry the skin with a paper towel.
6 Use a suitable gel to prepare the skin for better signal transmission.
Finding the best position for the electrodes is a matter of trial and
error. ( Page 91 ECG leads)
