There’s a nice article from the San Francisco Chronicle about the medical app mVisum, and how it was developed. The app is actually a product of the VA. It was originally made for the blackberry, but recently has been available for the iPhone. The article doesn’t mention the iPhone compatibility though.
Dr. Shroff and her team at DCVAMC launched mVisum in January 2009. mVisum helps cardiologists remotely diagnosis heart-attack-types and quickly communicate with relevant people who are working to help the patient. mVisum can vastly decrease the time it takes to get patients into appropriate treatment by making high-quality–and secure–EKG readings available to cardiologists on their smartphones. This way, they don’t necessary need to be inside the hospital. In the past, DCVAMC staff had to first locate–and occasionally wake up–off-site "interventional cardiologists" and then determine the quickest and most efficient way to distribute EKGs for diagnoses.
I couldn’t help but think of the interventional cardiologists who wouldn’t be rushing to the hospital as fast if they read a NSTEMI vs a STEMI. At the same time, the goal is to get this technology in all ambulances so the EKG will go directly to the cardiologist, and that ever important cath lab can get ready sooner.
