We are currently beta testing a device that can take your EKG and provide some level of analysis on your phone. If you are interested, we have currently have a private beta and have a few more openings! Of course we have much more planning in our production version. Please feel free to take a look: www.grektek.com. As the other reader mentions, cardiologists are the ultimate judges and even that can be difficult, but we have found helpful information can often be gleaned using our device and App.
