Pacemaker problems following a routine check?

Putting feelers out there to see if anyone has had a similar experience.

I had a routine test last week. Everything was fine. The device has been in for 7 years, and (usually) causes no issues at all. The following day, I went out for a run and my heart rate was not going up, as it should. I've been running for years, so I'm very aware of pulse rate whilst running. Usually, it averages 150-160. Since last week's check-up, the rate won't get about 135, meaning I get shortness of breath, aching legs and dizziness. This has happened once before following a routine test. I'm struggling to believe they would have altered a setting without letting me know. Hence, I am wondering whether the device takes a bit of time following its checks & tests. Anyone experienced something similar?

My rate response setting was switched on without me knowing, can’t remember what symptoms I got afterwards but I went back and they switched it off.

Contact your pacemaker clinic, or whoever did your checks.

During a routine checkup my EP told the tech to make an adjustment and when I questioned it he said you won’t notice or feel a difference. Unfortunately I don’t know what that adjustment was but after that my heart rate went over 100 just walking across the room and I had to use the elevator as I was so short of breath. The EP was then on vacation so I waited a week for his return to get the settings back where they were. Settings are comfortable again.

Yes, I also had problems when my EP made changes to pacemaker. I asked to get the settings back, and feel OK now.
