@pbr Hi and just to let you know we are not medical personnel but are patients and caregivers that share our own experiences to be a help to others. So I can't aswer the why on testing except it may have to do with insurance and some of these tests are restricted to a time period but I would think your Doctor would have said that. Now as to the increase in PVC's back when I had a pacemaker the readings would show those but I was told they were not a concern since they were not lasting very long. I don't know what normal to abnormal threshold is but mine usually would only last a fee.minutes at a time.and felt a bit weird but I was always more concerned with my main issue which was VT. So I would probably ask why She did not want.to repeat the test. You probably can even look at your insurance documentation to see if there is a limit on how many are allowed per year. I personally I was never treated for PVC's so im. not familiar with the med you mentioned either. I was already on anti-arrhythmia meds and my doctor said the PVCs were not bad enough.
I know I wasn't much help but maybe gave you a bit of confidence to not worry either.
Blessings
