Lol, I tried it just for fun and the first thing that happened was that I got a PAC. Not based on that I don't trust it, but it doesn't sound helpful :p

I had SVT and there was nothing I could do about it. It just did to me!
I wished and prayed for cause and effect... but it caused and I was effected. No control.

lol well i just found it interesting and thought heck i will pass this on.  It may work for some who pvc and pacs are caused by breathing issues.  I believe everyones stem from something different.
