Here’s a great concept, take an electronic stethoscope, combine it with an iPod/iPhone, and what do you get? A diagnosis tool that’s portable, and (relatively) cheap. The expensive part is the iPhone and the stethoscope (it’s $279.99), the app is cheap at $69.99.
It is a cool app though, you can display the heartbeat as a spectrograph or waveform in real time, save a recorded sound, and then email the sound clip as needed. Definitely a niche product, but very neat to see the convergence of technology. I’m definitely going to mention this to my doctor next time I see him.
