premature atrial contractions (PACs). Some of these were > 3 PACs in a row which they call runs or SVT. Some people live with thousands of these per day, your report shows a very light load of SVT. Only 37 of the PACs qualified as runs or SVT. Some folks will have thousands of them. Overall your heart probably beats 110,000 times per day, so 37 out of all those were PAC runs.
I've had similar problems, although I never actually fainted, although I came close a few times. I consulted and EP specialist, and yesterday, my cardiologist did an electrophysiological diagnostic catheter study, and during the study the doctor discovered that I had AVNRT, or atrioventricular nodal reentry tachycardia, the most common of all these types of issues. I was under mild sedation and aware of everything. I couldn't feel most of it, but did feel it when he burned the bad cluster of neural cells which were causing my double heartbeat and tachycardia. Afterward, the doctor told me that my condition was congenital and I've probably had this my whole life, which was true. However, it often gets worse as you get older. He also said it's a 94% chance that this will eliminate the tachycardia, which is pretty good. This was my best possible outcome. It has been just one day, but I'm feeling good and keeping my fingers crossed. The only uncomfortable part of the procedure was lying still for four hours afterward to allow for recovery, especially of the area at the groin where they inserted the catheters. I'm very glad I decided to see an EP and do this procedure. I wish you good luck.
