I ended up in the emergency room yesterday with runs of bigeminy and trigeminy. Though I dont ever have this problem, I do have a lifetime of rapid heart rate, usually at about 90-100 at rest, of course more if active. I had been taking Tylenol cold medicine (phenylephrine, no pseudoephedrine) for a cold x 5 days & ER doc thought that might be why I had the irregularities. I can feel every single PVC! No problem with it today, though my cold persists. Is there ANYTHING I can take that wont risk the return of the PVCs?
