6.1.3 Preparation for ECG Acquisition
- Since in leaning/half-leaning ergometry
electrodes cannot be placed on the
patient’s back or extremities, position the
electrodes as shown in figure.
- Configure your ECG unit according to your
needs and proceed as described in this
manual in Chap. 7.4 „Ergometry Program-
ing“ .
Ergometry process
- Microphone precisely above arteria brachialis
- Microphone position identified by red tab (cross)
7. Applying the Blood Pressure cuff :
* Feel for the position of arteria brachialis and position microphone (identified by
the red tab) precisely above arteria brachialis (E).
* Apply the airless cuff tightly at upper arm in order to prevent slipping during the
ergometry test, however not extremely tight.
* Apply cuff directly on skin, i.e. you must not use an intermediate layer out of
cloth, paper, .....
* The cuff should not touch the elbow.
* After application of cuff, the patient shold use the arm rest (F) as support (and
reduce thereby movement artefacts)
* Check that the cuff tubing is unimpeded and will not knock against any objects
when the patient has placed his hand at the handlebars and starts pedalling.
Move the armrest (D) accordingly toward the head or toward the leg. The con-
necting tube for the cuff should be as free as possible and not crimped or pinched
in any way.
* Advise the patient to keep his arm as still as possible during an ongoing
blood pressure measurement, and especially to avoid extreme contraction
of muscles of the upper arm.
