Although CES focuses on consumers, we shouldn't forget that doctors are consumers, too. This year, AliveCor showcased its heart monitor case for the iPhone 4 and 4S. This device uses AliveCor's proprietary wireless communication protocol to communicate and requires no pairing between the iPhone and the Heart Monitor. The FDA-approved medical device is intended for use by doctors to record, display, store, transfer and evaluate single-channel electrocardiogram (ECG) rhythm strips.
In clinical trials, AliveCor's Heart Monitor demonstrated clinical efficacy. Of course, this has real-world interest, too: The next time someone at a restaurant or airport develops chest pain, a doctor may pull out an iPhone to accurately diagnose a heart attack.
Price: $199; available only to U.S. licensed medical professionals
