I have a long history of AFib and have received Cardioversion twice. I was experiencing skipped beats every three or four beats and became concerned that I might be in AFib again. Thankfully my PCP assured be that I was not and that what I was experiencing was fairly common. I decided to explore getting a portable ECG device and found the AliveCor® KardiaMobile EKG Monitor on Amazon. I read the reviews and found that many of AliveCor®'s customers were disgruntled over the $10 per month reoccurring cost for their "premium" service. One of the reviewers specifically named SonoHealth EKGraph as an alternative that provided all the same functionality but did not charge for a "premium" service or a connection to a cell phone to work. I searched Amazon for EKGraph and SonoHealth but found that they didn't have that brand, so I widened my research to the WWW and soon discovered SonoHealth's website, and from there reviews.io. I have not yet received my EKGraph, but I'm assured by the US Post Office that it will be arriving next Tuesday. When I have evaluated the product and gotten my Doctor's opinion, I'll leave a product review.
