To use the device, patients place two fingers on the back of AliveCor’s iPhone case and rest them on the large electrodes. The case can also be pressed directly against a patient’s chest for ECG, or electro-cardigram monitoring, purposes. Data from the electrodes wirelessly passed from the case to the iPhone, where it can be analyzed or send to the cloud for storage. The case runs on its own coin-cell battery, which is good enough for an estimated 12,000 scans at 30 seconds in length.
While the case and supporting app won’t analyze the data — that’s for an actual medical professional to; at least for now — the idea of putting the data in the cloud is intriguing. A doctor could remotely view the data for analysis, for example. Or, if the device were actually sold directly to consumers, a doctor’s visit could done virtually: The patient could use their own AliveCor case and iPhone to send heart rate data to a local physician at regular intervals.
What’s next in this area of health monitoring meshed with smartphones? A Star Trek tricorder of sorts. The Scanadu Scout doesn’t have FDA approval like the AliveCor case does, but it sounds promising. The small device measures heart rate, level of oxygen in your blood, pulse and body temperature to work with a smartphone and actually diagnose more than a dozen health issues.
