A pacemaker (internal or external) intentionally causes currents to flow in the patient to stimulate the heart. That is acceptable. There are many therapies that use electric current. Some that I can think of immediately are anesthesia, bone repair, brain stimulation, drug therapy, muscle stimulation, and pain relief. However, applying 50 or 60 Hz current is not beneficial and therefore is not acceptable Medical systems are NOT exempt from patient leakage current limits.
