| The
electrocardiogram is a medical exam in the cardiology
area where is made the registration of the variation of
the electric potentials generated by the electric activity
of the heart.
The heart presents electric activity for variation in
the relative amount of present ions inside and out of
the cells of the miocárdio. This cyclical variation
generates difference of concentration of the referred
íons in the periphery of the body. Sensitive Eletrodos
placed in specific points of the body they register this
electric difference.
