Faradic
Effect
The
pulsed
current
causes
the
neuro
‐
muscular
stimulation,
originated
by
stimulation
of
physiologic
process
of
ionic
exchange,
responsible
of
the
transmission
of
stimulus
that
cause
muscular
spasms
and
cardiac
symptoms
of
extra
systole
and
ventricular
fibrillation.
The
effect
of
this
stimulus
is
known
like
faradic
effect
and
it
is
expressed
by:
R=
I
/
√
F
The
physiologic
system
of
stimulus
transmission
follows
a
limit
curve
in
which
the
pulsed
currents
or
by
low
frequency
produce
an
impulse
of
stimulation.
By
alternating
current
in
high
frequency
(higher
than
200
kHz),
used
in
the
electrosurgical
needle,
don’t
have
neuro
‐
muscular
reactions
(the
change
of
polarity
is
so
fast
that
the
patient
doesn’t
have
consequences
at
a
level
of
the
neuro
‐
muscular
reactions),
and
there
isn’t
an
electrolytic
damage
of
the
organism.
For
this
reason
all
the
equipments
generator
of
the
high
frequency
for
surgical
use
(electrosurgical
needle)
work
on
base
frequencies
higher
than
300
kHz
so
that
they
don’t
produce
electric
stimulation.

Electrolytic
Effect
The
use
of
high
frequency
currents
reduces
the
electrolytic
effect
(ionic
division)
in
the
tissues,
caused
by
the
shortest
period
of
unidirectional
conduction
of
the
current.
