Change to my pacemaker

[Beatbox21]

HI, i had a pacemaker check in September and due to an non sustained VT in the early hours whilst i was asleep the electrophysiologist increased my range from 50bpm to 140bpm where i used to be at 130bpm. She said that is all she changed, nothing else.

I called up monday last week as the change the technician made did not sit ok with me. I kept feeling flutters, which i did not feel this strongly before she made the changes. I went back for them to change it and i still don't feel ok. They told me originally, the only change, is an increase of 10bpm and said they put it back, but i feel the same. So it feels like they have done something they are not telling me about or they have not taken time to explain what i may feel like.

Can i ask for any advice as i need to call them this morning to ask them to change it. As they said they did this already what shall i do. Before my appointment in September i did not have this feeling. I am a bit stressed by this. Please does anyone have this experience before and what shall i do? Thanks
