Portable, Personal ECGs and Security

Several months ago I heard the exciting news that a doctor invented an iPad app to replicate an electrocardiogram at a fraction of the cost of its being done in a doctor's office. I'm trying to understand why the use of this hasn't accelerated. Doctors' offices are often busy. Insurance companies are always trying to control costs. And, of course, this could help prevent heart attacks and strokes. So what gives?

I can't answer that part, but I can remind health care providers and insurance companies of one thing: security on mobile devices must not be overlooked. This app is an awesome idea. Someone holds the iPhone in his hands and it can replicate the measurements of an ECG and send it to the doctor. But that also means tracing the patient's name, address, date of birth and electronic medical records, which often have the Social Security number as well. No pun intended, but you don't want a patient to have a heart attack because he found out that his identity was stolen while doing an anywhere ECG via an app!
