Hi, my condition is an AV Block 3rd degree, and had a Biotronik Enitra 6DR fitted 3.5 years ago, following which I had no further symptoms at all. About 4 weeks ago I noticed during light exercise a tightness in my chest, along with light headedness. This continued for some days, and after a visit to my doctor he suggested I have my pacemaker checked.
They checked and said the pacemaker was performing normally, but did notice that about 4-5 weeks previously the "Pacing Trends" graph had jumped suddenly from an average of 12% over the previous 7 months to 100% (I have a photo of the graph). This seems to coincide with when my new symptoms showed up. Just wondered if this is something I should be concerned about?
