After my AVR and resulting pacemaker implant last November I have been struggling with breathlessness every time I walked fast, or uphill etc, but on the flat at a gentle pace I was fine. I mentioned it at my first pacemaker clinic but it was only a month after my op so thought it was that. Had my check up today and apparently it was set at a maximum of 110 bpm, which Chris thought was very low. He explained that my heart was trying to beat at 115bpm but the pacemaker was only firing at 110bpm, hence getting breathless. He has now reset the maximum to 130 and I already feel better. So nice being able to breath! He is going to see how I am in six months and may tweak it again, but I did assure him I had no plans on running any marathons, ever!
