The use of therapeutic ultrasound should be okay and is not contraindicated for pacemaker recipients. There is a remote possibility of single beat inhibition of the pacemaker, which may result due to the pacemaker’s inappropriate sensing of the ultrasonic waves.

This possibility decreases with the therapy distance from the pacemaker. Do not use therapeutic ultrasound within six inches of the pacemaker. Inhibition is less likely if the pacemaker is programmed to the bipolar mode.

If you feel dizzy, light-headed, or short of breath during your treatment, notify your physical therapist and immediately discontinue the therapy.
