This is very popular. There are several products that take ECG samples at timed intervals and submit them in several different ways.

In addition these devices can be used to take 12-lead EKG measurements in transit (e.g. inside the ambulance) and send them to the doctor for analysis before the patient arrives.

I'm very surprised that they're hosting these services on EC2. The company I worked for recently finished building a huge highly-redundant data center specifically designed for hosting this kind of medically-sensitive information. I'm willing to bet it was a bit more fortified than even Amazon's.
