Abstract

An external cardiac device includes a detector used to detect an abnormal condition of a patient, a controller operating the defibrillator in response to a command and a therapy delivery circuit that delivers appropriate therapy, such antitachycardia, defibrillation or antibradicardia therapy. The defibrillator is attached to a patient by any attendant or bystander and a signal is sent to central station to alert a clinician that the device has been activated. Once the device has been attached, the defibrillator is adapted to monitor the patient and to transmit information to the remotely located operator. The operator then decides what kind of therapy is required and transmits an appropriate command to the device. In one embodiment, the device includes a base station communicating with the central station and a pulse generator which may be separable from the base station. In another embodiment a unitary pulse generator is used with means for communicating with the clinician directly. The device includes a speaker and a microphone to allow the operator and the attendant and/or patient to communicate with each other.
