We now know that Apple held closed-door talks with Tesla, a meeting of two innovative companies that hints at a number of possibilities. But buried in that same report from the San Francisco Chronicle is the news that Apple may also be preparing to release a heart-attack prediction device.

According to the report, Apple is developing sensor technology that would be able to predict heart attacks. The effort, led by audio expert Tomlinson Holman, the inventor of THX and 10.2 surround sound, will reportedly focus on the sound blood makes as it travels through a person's arteries.

However, in order for Apple's supposed sensor to monitor the sound of a person's blood, that device would likely have to be worn on a person's body. Therefore, this new information directly points to the continued rumours of an upcoming Apple wearable device, commonly referred to as the iWatch.

The iWatch implications of the San Francisco Chronicle report are further backed by last week's news that Apple hired medical-device expert Marcelo Malini Lamego. What's more, a report in January claimed that Apple is also working on new health-focused apps for iOS.

If this new report regarding Apple's heart sensor research pans out — barring a surprise move by the company to enter the medical scanner bed industry — Apple's rumoured iWatch will turn out to be far more broadly impactful than anyone could have guessed.
