An EKG kit for fun and profit

Yesterday I order an electrocardiograph kit for $75. It includes the electrocardiogram electronics, the Arduino embedded computer that receives the signals from the EKG and converts them to something more usable for viewing, analysis and archiving. It also includes the cables I need to hook it up to people and to another computer. I really do not want to hook the EKG up to another computer with a cable. I want to use Bluetooth, so I bought another $99 computer from NewEgg and the Bluetooth accessories I need to talk to the EKG embedded computer. This should be educational.
