A defibrillator locating system and method enables would-be responders to quickly identify defibrillator location for effecting prompt defibrillation. The system may be said to comprise a number of spaced heart-shaped signal-transmitting devices, a signal-receiving/alarm device, and an automatic external defibrillator pair-positioned in visual proximity to the signal-receiving/alarm device. A responder may send a signal from any of the transmitter devices for activating the nearest receiving/alarm device, the latter of which activates an alarm signal for guiding the responder toward the automatic external defibrillator. The alarm signal is preferably auditory and has sufficient intensity whereby the responder may be able to aurally perceive the auditory signal and follow the same to the defibrillator site along an unobstructed pathway. The removably attached defibrillator enables the responder to quickly carry said defibrillator to a cardiac emergency site.
