Abstract

An atrial defibrillation system includes an implantable atrial defibrillator including an atrial fibrillation detector and an atrial cardiovertor, and an external communication device dimensioned to be hand-held and including an RF transmitter for transmitting a command signal to the implanted defibrillator. The implantable defibrillator includes a receiver for receiving the command signal, activation means responsive to receipt of the command signal for activating the atrial fibrillation detector and the atrial cardiovertor if the atrial fibrillation detector detects atrial fibrillation, and an RF transmitter for transmitting an acknowledgment signal to the external communication device responsive to the receiver receiving the command signal. The external communication device further includes a receiver for receiving the acknowledgment signal and an indicator for providing a perceptible indication responsive to receipt of the acknowledgment signal.
