TRAINNG UNIT FOR THE PACMAKER EMERGENCY INTERVENTION SYSTEM

A training unit generally includes a processor, a magnetic field sensor, a plurality of control switches, and a message and data output device. Placing a PEIS magnet, constructed in accordance with the ISOWD 14994 standard, adjacent to or in contact with the training unit activates the magnetic field sensor, a condition detectable by the processor. Activation of the switches determines which of three modes the training unit will operate. In an instructional mode, the process provides instructional messages to the operator via the message and data output device, which preferably includes a display and an audio speaker. In a coached mode, the training unit informs the operator when to place the magnet adjacent to or in contact with the training unit and when to remove the magnet in accordance with the timing intervals of the PEIS entry code. In a practice mode, the operator initiates and completes the entry code using a PEIS magnet without coaching. The processor detects the presence of the PEIS magnet, and determines whether the operator correctly performed the entry code correctly. If the operator completes the entry code in either the coached or practice modes, a simulated ECG waveform indicative of a patient's surface ECG upon successful completion of an entry code is shown on the display. Conversely, the training unit informs the operator of a failure by the operator to successfully complete the entry code.
