Multiple electronics in close proximity
New member here who just found the club. I received my first pacemaker almost 25 years ago at the age of 15, am non-dependent, have done great ever since, and had my 4th device impanted last May. Recently though, I have had a wierd, random problem I am hoping someone here may have knowledge on.
I teach University-level classes and taught remotely during for the past year during COVID, until about a month ago. During the COVID pandemic universities "teched up" in their classrooms, which now house a number of broadcasting electronics (pre-amp, antennas, mic array), alongside all of the normal electronics (computer, overhead, etc). Classrooms are now quasi-recording studios, with seating. Also, all of the tech, except the projector & TV's, are housed in the lecturer's podium.
Each time I stand behind the podium and lecture I begin to feel dizzy, lightheaded, and yesterday I almost hit the floor. The non-cardiologist doc says I am fine, physicially. Unfortunately, my cardiologist has a 2-month wait to get his assessment.
Does anyone know if the electronics in the podium, about 18"-2' away from me, could be producing enough EMI to affect my unit? I know the unit is shielded from most EMI, but perhaps some of the new tech or the combination of all of the tech produces enough EMI to make my unit act up?
