Review on sec Portable Heart Rate Monitor: Track Heart Rhythm with Smartphone App - Wireless Home Monitoring Device for iPhone/Android Tablets by Quvarious Evans

As someone who can read heart monitors, I am very impressed with the clarity this device offers. He records in Lead II and records for 30 seconds. However, you must be silent, otherwise there will be some kind of artifact. Additionally, you need to connect to the app, which is easy to download but a bit confusing on its own. Once you are able to write it down, it will be plotted on graph paper so the arrhythmia can be accurately identified. From the PR interval to the isoelectric line, everything is clearly displayed. You also have the option to save the recording as a JPEG or PDF. For me, this device is best suited for those who can interpret the recording. It's not fair to compare the display to a real heart monitor, but it will do the job well. However, I'm glad I got it.
