PAC's increase as B.P. decreases?

Hello
I've been diagnosed with PAC's for 25 years, noticed them from time to time but once diagnosed, never thought that much about them. They are not enjoyable, but at the same time, not that
serious.
About 3 years ago I had extensive lithotripsy (3K pulses) to remove a large kidney stone, since then I've had several other stones, none that required ESWT, but noticed a general rise in my B.P.   It went, over a period of 2 or 2 1/2 years,  from 130/82 to 180/107 on a regular basis.  Suspicions arose that perhaps renal artery stenosis had occured and I was placed on a number of B.P. meds, none of which helped.
My most recent MRA showed no stenosis of the main artery to either kidney.
At the same time as the MRA, I was placed on Hydroclhlorothiazide.  Within a few days, my blood pressure had dropped to 107/72, sometimes even lower.  
At the same time, my incidence of PAC's increased quite noticeably.  I had been given propanolol
to use if needed for the PAC's and took it rarely.  Now I need it often twice a day.
Is there any relationship between the lowered B.P. and increase in PAC's or am I just noticing them
more due to the lowered B.P.?    I can live with the PAC's as I much prefer that to the hypertension
problem, just wondered if there is a connection.
I'm taking, in addition to the hydrochlorothiazide, Benicar 20mg/day and Coreg 10mg/day.
Any thoughts/ideas would be appreciated.

Honestly, I don't know much about your situation, but I do know for myself that I typically feel them more often the slower my heart rate is, and I do have tachycardia, so when it does get down in the 70s, I notice them more often. It might be that you only notice your blood pressure before, and now that it's taken care of, you now are noticing your pacs more. I'm not sure though, just a thought.

Yes, I notice my PAC's when my heart rate is slower/bp lower.
