Can Lucha T8 device be used by a person who has a pacemaker?

For all users who have electrical stimulators of any kind (cardiac pacemakers, gastrointestinal electrical stimulators) or implanted foreign bodies made of metal (artificial heart valves, orthopedic endoprostheses, etc.), for now we do not recommend using the device because we do not have enough experience yet. We do not know whether the Schumann frequency can interfere with the heart rate.
We assume that there are no contraindications, but we do not recommend it for now.
