Boston Scientiffic Accolade L331. Settings: DDDR, RYTHMIQ - Off, Lower Rate Limit 40, Max Tracking Rate 135ppm, Paced AV Delay - 80-350ms, PVARP - 250-300ms. VRP - 250-250ms, Minute ventilation and Acceleometer both on.
I'm a 76yo life long amature cyclist, DX'ed with AFib at 65 and Sinus Node Dysunction in May-June '23. S/P PPM Placement in July '23 and successfull cardiac ablation in August '23. My Boston Scientific Tech is a cyclist and knows what I want and need out of my PM. So far, so good. I can reach and sustain Zone 4 exercise and will touch zone 5 periodically (Polar Ignite wrist pulse monitor). I've tried a chest strap and it produces unrelaible data due to, I'm told, PM interference. I've also used the excellent 4th Frontier system - same interference and ECGs are whacked.
My last in clinic device check on January 25th, '24 shows a 63d PVC count of 166.3K and a 43d count of 60.7k (2640 PVCs/d and 1429/d respectively). Both my cardiologist and EP cardiologist have seen the Device Check Reports and aren't concerned about this. I am.
What I orginally thought was inappropriate pacing at resting HR (a periodic and regular thumping sensation that starts and stops during the day) may be PVCs both chained runs and single beats. These symptoms do not appear under excercise stress at HRs above 90 BPM. The PVCs seem to disappear - the expected occurrance as the QRS interval shortens at higher HRs. Based on my complaint, my tech at my EP's direction shortened the VRP window from 250 - 300ms to 250 - 250ms on a December 14th '23 in clinic device check. Didn't seem to help reduce PVCs. I don't beleive the EGMS are granualr enough to display the suspect PVC's morphology and a recent 12-lead surface ECG didn't catch a run of them so, docs aren't worried. I've read some literature that reports PVCs being induced by a PM. Raising the Lower Rate Limit to 60 bpm cleared the PVCs up in the study arm. What is the group's take on my PVC count at the last in clinic device check and my PPM settings in general.
