Pacemaker pulse detection
When the device examines a patient with a pacemaker, it recognizes the pacemaker signal within a set range
according to technical data and displays them graphically on the record. In this case, the device does not create a
diagnosis, since the pacemaker pulse interferes with the diagnosis program.
In this case the device only creates analysis, which the pace impulse does not interfere with, but due
to morphological differences there may be inaccuracies in the numerical data.

Checking electrode and amplifier operation
If the input side of the amplifier does not work properly or there is cable or electrode problem, the device blocks
automatically and initializes the filters. After blocking the device checks if the error state continues. If so, the
device repeats blocking and filter initialization.
