Abstract
Disclosed is a bio-electic interface adapter with at least two large area defibrilation electrodes and sufficient smaller precordial electrodes present therein to allow standard twelve lead ECG monitoring. The defibrillation electrodes can be affixed to the bioelectric interface via perforations, or by a functionally similar approach, to allow easy detachment in use. The bioelectric interface adaptor preferably has an undulated outer edge geometry, and provides electrodes for forming limb leads, optionally allowing use of the defibrillation electrodes as Right Arm and Left Leg electrodes. Limb lead forming electrodes are preferable affixed via perforations, or by a functionally similar approach, to allow easy detachment and deployment to conventional limb electrode locations, in use.
