I left a five star review under "company" an unfortunately there is no room to upgrade to six stars, my EKGraph was scheduled to arrive today, but actually came on Saturday, hurray! I have been using it for the last three days and it has performed as advertised. I was able to send some strips to my PCP and am awaiting feedback from her. The only thing I would like is if it could distinguish AFib from the general Arrhythmia. The only things I've seen are a couple of "Accidental VPB"s, general classification of "Arrhythmia", and "No Abnormalities". Since I have a history of AFib, I would like to see those flagged instead of having to look for P waves in the strip.
