I have a question about Holter results that I recently requested a copy of from November of last year. I was feeling a new palpitation of a "fluttering" in my heart when I stretched after waking up. From the joural that I kept with the Holter, they could not connect what I was feeling with anything unusual. However, on the report I just received, it says I had 2 supraventricular runs during the 48 hours, both occurring about the time I wake up, on each morning I wore the Holter. The longest supraventricular run was 25 beats on the first day, and the fastest run was on the second day at 123 bpm. I had no afib and no ventricular runs, and 41 premature supraventricular "prematurities" and 56 ventricular prematurities during the 48 hours. So my question is, what is a "supraventricular run"? I get bigeminy often. Is that considered a supraventricular run? Just curious.
