Abstract: In a pacer for artificial heart stimulation, the stimulating pulses produced are inhibited when the pacer detects that natural heartbeats are present. If the pacer detects electrical pulses at a frequency higher than a predetermined threshold frequency, resulting from external interference, the inhibition is suspended, and stimulating pulses are supplied. When interference is detected, the pacer may be arranged to generate stimulating pulses at a frequency higher than normal to avoid the possibility of the artificial pulses competing with natural stimulating pulses.
