Had 3 month post-implant checkup last week. Chronic settings set and floor set at 60bpm. Cardiologist said that the interrogation report showed some Afib and LOTS or rapid bursts of Atrial activity. Recommended I see my EP. Saw EP today and he did another interrogation and there were a bunch more of those short bursts of atrial activity. He said "we're going to break the elephant down into manageable pieces" and decided to raise my floor to 70bpm and turned on Rate Response and Minute Ventilation. I had told him that I have had absolutely no energy since implant. The changes today he said were to start helping me feel better. He said that sometimes upping the low setting up from 60 will reduce the short bursts of atrial activity that could be triggered from the lower rate. He did a decent job explaining Rate Response and MV and said that there is usually some tweaking needed on those features to dial in the best settings for my situation. The interrogation showed that since last week my heart rate has not gotten over 71bpm (other than the short bursts) and that was the main reason for cutting Rate Response and MV on. Said he wants to see a bigger spread of heart rate ranges.
it does feel a little weird. Prior to implanting the PM my normal heart rate was in the low to mid-50's. After implant the HR stayed pretty dang close to 60bpm. Not used to 70bpm resting..... LOL
I have also noticed that it doesn't take too much activity to feel my HR increase now with the new settings. Will take some getting used to. Go back to EP in 3 weeks for a checkup. Will tweak settings if needed and if the rapid bursts are still occurring he said we will tackle changing my meds up.....
