Implantable cardiac arrest monitor and alarm system
First Claim
1. A cardiac arrest monitor and alarm system comprising:
- a subcutaneous 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 medical device, the microdevice detecting a deviation from a normal heart electrical activity; and
an external receiver detecting a signal from the microdevice and activating a programmed annunciator circuit to activate a local alarm, and activate a communication link automatically transmitting an alarm and the electrocardiographic signal to a remote transceiver, wherein a position identifier allows identification of a patient'"'"'s position.

Abstract
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.
