Electrocautery or diathermy device: Diathermy and electrocautery
equipment should not be used. If such devices must be used:
1. Keep it as far as possible from the pacemaker. 2. Set it at
minimum intensity. 3. Use it briefly.
External defibrillation: If the patient must be defibrillated, it is
recommended that the paddles be placed at least 10 cm from the
pacemaker, along a line perpendicular to the axis formed by the line
connecting the leads to the pacemaker.
Internal defibrillator: Use of the pacemaker is contraindicated in
implantable defibrillator patients.
Radiation therapy: Avoid exposure to ionizing radiation. Betatrons
are contraindicated. If high doses of radiotherapy cannot be avoided,
the pacemaker should be protected from direct exposure, and
pacemaker operation should be monitored continuously. Resulting
damage may be immediately undetectable. If irradiation of tissues
close to the implantation site is necessary, it is recommended that
the pacemaker be moved. As a safety measure, temporary
pacemaker back-up should be immediately available.
Lithotripsy: The risks associated with lithotripsy are limited if the
cardiac pacemaker is not implanted in the abdominal position.
However, in order to avoid all risk of ventricular or atrial fibrillation,
shocks should be administered synchronously with pacing.
Ultrasound: The pacemaker should not be exposed to therapeutic
levels of ultrasound.
Transcutaneous Electrical Nerve Stimulation (TENS): TENS may
interfere with pacemaker function. If necessary, the following
measures may reduce interference: 1. Place the TENS electrodes as
close together as possible and as far as possible from the pulse
generator and leads. 2. Monitor cardiac activity during TENS use.
