The iPhone ECG heart monitor from AliveCor has recently received FDA approval in the US and is now available by prescription. Currently, the system is compatible with the iPhone 4 and 4S and includes a phone snap-on sensor for rapid ECG readings. Users hold their iPhone with both hands and place their fingers on the sensors to have their ECG readouts taken. The readings can then be displayed, stored and transferred easily. Data is stored in the cloud allowing users to review, analyze and print through AliveCor’s HIPAA-compliant website.
