What does a doctor do if the pacemaker is not functioning?
If your pacemakers are not functioning correctly, then a doctor
will often use a defibrillator to shock them back into normal
usage. Your pacemakers send electrical pulses to your cardiac
muscles signaling them when it is time to contract. When these
pacemakers (cells) are not functioning correctly, then the doctor
will use the defibrillator to change their electrical currents,
this way the pacemaker cells are fixed.
