23. A control system for an electrotherapy device comprising:

a controller;

a first memory communicating with the controller, the first memory containing instructions for use by the controller to operate the electrotherapy device; and

a second memory communicating with the controller via a memory port, the second memory containing instructions for use by the controller to operate the electrotherapy device without instructions from the first memory.

24. The control system of claim 23 further comprising means for transferring communication between the controller and the first memory to communication between the controller and the second memory.

25. The control system of claim 24 wherein the means for transferring comprises a memory control mechanism.

26. The control system of claim 25 wherein the memory control mechanism comprises a button.

27. The control system of claim 25 wherein the memory control mechanism comprises an actuator responsive to the attachment of the second memory to the memory port.

28. The control system of claim 24 wherein the means for transferring comprises instructions causing the controller to communicate with the second memory.

29. The control system of claim 23 wherein the controller and the first memory comprise means for writing information to the memory port.

30. A control system for an electrotherapy device comprising:
