Implantable cardiac arrest monitor and alarm system

摘要

A cardiac arrest monitor and alarm system including an implantable medical device having at least three subcutaneous electrodes positioned with respect to a heart organ and forming a subcutaneous orthogonal lead configuration to continuously monitor an electrocardiographic signal of the heart organ. An implantable microdevice, operatively connected to the subcutaneous 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 and activate a communication link automatically transmitting an alarm and the electrocardiographic signal to a remote transceiver.
