Aloha Philip Curtis,
Good question. When asked about this, Chunyi mentions to put out the intention before you start, that the healing energy to work with the existing medications, pacemaker, etc for yourself or your friend's best.
Spring Forest Qigong is message healing and the energy has an information piece to it as well as being intelligent.
Much Love, Shawn
