Abstract

A cardiac arrest monitor and alarm system including an implantable medical device having at least three electrodes, preferably but not necessarily subcutaneous, positioned with respect to a heart organ and forming an orthogonal lead configuration to continuously monitor an electrocardiographic signal of the heart organ. A microdevice, preferably but not necessarily operatively connected to the medical device, detects a deviation from a normal heart electrical activity and emits a signal to an external receiver. Upon verification of the signal from the microdevice, the external receiver activates a programmed annunciator circuit to alert bystanders to deploy an AED and/or activate a communication link automatically transmitting an alarm and the electrocardiographic signal to a remote transceiver.
