Abstract
An adapter for connecting combination electrodes to a defibrillator/monitor/pacer. The adapter isolates the pacer from the defibrillator when a defibrillation pulse is applied over the combination electrodes. In a first embodiment of the adapter, the pacer is conductively connected to the combination electrodes only when the pacer's power supply is turned on. In a second embodiment of the adapter, the pacer is normally connected to the combination electrodes, but is disconnected when the defibrillator/monitor/pacer is analyzing a patient's ECG or when the defibrillator is charging to enable it to deliver a defibrillation pulse. Also provided in the adapter is a contact assembly for connecting the adapter to defibrillation paddles from the defibrillator.
