Isoelectric line
The term isoelectric line in an electrocardiogram or electroencephalogram refers to the sections of the route in which no potential difference can be measured between two recording points, consequently neither a positive nor a negative deflection can be seen on the graph. In the case of the EKG, this means that all heart muscle cells lying between the two recording points are in the same state of excitation (excited / non-excited).
In the case of asystole , in which the permanent isoelectric line in the EKG is caused by the lack of electrical activity in the heart, it is called a zero line .
