I experienced PVC's during my first EKG yet the "clinician" reported normal. I had to contact support before I got a response after 4 days. Their explanation was that there had to be 2 PVC's within the first, I think it was, 4 seconds of the EKG for it to be recognized. Really?
I have found it easy to use as an effective monitoring tool for atrial fibrillation with the ability to maintain and transmit a historical record to others .
