I have no experience at either golf or using a pacemaker, but as no one has responded I'll offer I associate the electronics/clock implant with being in the upper chest area and I will guess your concern is well founded.
I doubt it would be advised to move the location far from the heart, the locations noted...but I do not know.
The few examples I have with friends and relatives is the pace maker hasn't prevented any of their (elderly) physical activities, which does not include golf.
Hope you get something more useful.
My son, daughter and I all have pacemakers and it doesn't have any effect on their golf game (I don't play). The device is located on the upper left.
