It is a form of mediation.

You regulate your breathing, your heart beat slows, your mind is fixed.

Not surprising that it would lower your blood pressure.

I shall have to add wall sits to my repertoire. As it is I go out into the hangar at work and bust out 20 push-ups, & 20 sit-ups once an hour to deal with stress, and to get away from my desk for a few minutes. The occasional wall sit might be worth a go.

Long slow inhale with fast short exhale increases energy while fast inhale with long slow exhale calms the body.

You regulate your breathing, your heart beat slows, your mind is fixed.

Also control the diaphragm up and down to get a bigger volume of air in the lungs.

Measure your BP before and after

Lowest I managed was 112/57/54

Maybe not so much. I've been doing isometric holds against resistance for five years now. No meditation to it -- it's a killer what it does to your muscles and it shoots my heartrate up pretty well, even for a short 10-second hold (if I use dynamics as well). My BP has fallen close to 15%, systolic and diastolic and vascularity was noticeable after the month week.

I'd love to know why isometric holds work, but I don't think meditation plays a part. Of course, anecdotes are just that for a reason. :)
