This example shows data from a syncytium of cardiac cells treated with a biphasic 2 V bipolar
stimulus pulse field applied to electrodes No 36 and No 46. Please see the schema below.
The blanking artefact is in the range of 10 μV that is a negligible value in comparison to
the amplitude of the cardiac field potentials ranging from a few hundred μV to several mV.
You see the stimulation artefacts on all electrode channels.
The response of the cells to the stimulation is instantaneous in the cells near to the pulse.
The cells recorded in the periphery of the syncytium need about 3 to 13 ms for their response
to the stimulus pulse. This is the propagation time during which the electrical pulse is spreading
in the cell syncytium.
