Cardiac arrest monitor and alarm system
First Claim
1. A cardiac arrest monitor and alarm system comprising:
- a medical device having at least three electrodes positioned with respect to a heart organ and forming an orthogonal lead configuration to monitor an electrocardiographic signal of the heart organ;
a microdevice operatively connected to the medical device, each of the at least three electrodes positioned on an exterior surface of the microdevice, the microdevice detecting a deviation from a normal heart electrical activity; and
a plurality of external receivers, at least one of the external receivers 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.

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.

24. A method for detecting a deviation from a normal heart electrical activity and transmitting an alarm upon detecting the deviation, the method comprising:
-
monitoring an electrocardiographic signal of a heart organ using a medical device;
amplifying and digitizing the electrocardiographic signal;
executing a set of instructions to analyze the electrocardiographic signal;
detecting the deviation from the normal heart electrical activity and upon detecting the deviation, transmitting the alarm and the electrocardiographic signal to at least one of a plurality of external receivers electromagnetically connected to a microdevice operatively connected to the implantable medical device;
activating a programmed annunciator circuit to deliver the alarm and establish with a remote transceiver a communication link providing a communication between a person alerted by the alarm and the remote transceiver;
transmitting the electrocardiographic signal to the remote transceiver;
automatically providing an automatic location identification signal; and
activating a telephone to automatically dial a programmed emergency telephone number. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
