The present invention takes the form of a device for training a user in defibrillation technique. The device includes a non-conductive belt that encircles a chest of a typical training simulator. The device includes conductive studs disposed in the AP or AL position, and therefore allows for training of the AP or AL defibrillation technique, respectively. The device can be used in conjunction with a high-technology simulator. In such a case the conductive studs redirect simulated cardiac rhythm signals and defibrillator electricity, allowing for the simulation of defibrillation in the AP position. The device can also be used in conjunction with a low-technology simulator or a pillow to provide AP and/or AL defibrillation functionality. In such a case, a rhythm simulator is used to simulate heart rhythm and dissipate defibrillation energy.
