Electric activity that goes through the heart, can be measured by external (skin)electrodes. The electrocardiogram (ECG) registers these activities from these electrodes which have been attached on diffrent places on the body. In total, are twelve records to be calculated using ten electrodes. | |||
The ten electrodes are: | |||
* '''de extremiteitselectrodes:''' | * '''de extremiteitselectrodes:''' | ||
** LA - | ** LA - left arm | ||
** RA - | ** RA - right arm | ||
** N - | ** N - neutral, on the right leg (= electrisch aarde of nulpunt ten opzichte waarvan de electrische spanning wordt gemeten) | ||
** F - | ** F - foot, on the left leg | ||
It makes no diffrence whether the electrodes will be attached proximal or distal on the extremities. ''Echter'', it is better not to ''afwisselen'' it. (eg. an electrode on the left shoulder and one on the right wrist). | |||
