The AliveCor Heart Monitor is a mobile accessory and an application. It’s cleared by the FDA for sale in the U.S. to licensed medical professionals and prescribed patients to record, display, store, and transfer single-channel electrocardiogram (ECG) rhythms.
IT seem really easy to use, this the description provide by the referred website: “To generate a Lead I ECG, rest the electrodes on the fingers from each hand (iPhone Home button should be on the right). The app senses skin contact on the sensors and when an acceptable connection is made it counts down to initiate the ECG recording. Set your app to take 30 second, and up to continuous, rhythm strips. While the ECG records it will also display heart rate. ECGs over 10 seconds are automatically saved in the app for review and can be annotated with details or can be discarded. ECGs can be inverted if needed and gain and paper speed adjusted as well. Our clinical-quality, single-channel ECG recorder leverages the power, display, and communication capabilities of the mobile phone.”
