Abstract

A medical alarm communications system comprises a pager like device to be kept near a patient. The pager like device communicates medical alerts regarding the patient to a remote central station, which can provide therapeutic and/or diagnostic assistance by communicating to the pager like device. When the pager like device determines that an alert should be sent to the central station, it attempts to establish communication with the central station according to a primary communication protocol. If this attempt is unsuccessful according to some predetermined criteria (e.g. too much time has elapsed before communication is established), then the pager like device generates a message to the patient indicative of the failure, and The attempts to establish communication with the central station according to a secondary communication protocol.

Claims

1. A cardiac monitoring system having a patient monitoring system and external equipment located remotely, comprising:

a. the patient monitoring system including a patient implanted device and an external device located near the patient;

the implanted device configured to (1) record signal data from the heart, (2) to analyze the signal data to detect at least one type of cardiac event, said implanted device being configured to categorize said at least one cardiac event as an event which is selected from the group of urgent event and non-urgent event, and (3) to transmit data wirelessly to the external device;

the external device configured to provide communication with the implanted device, a patient, and with the external equipment located remotely based upon the categorization transmitted by said implanted device, said external device being configured to transmit and receive data to and from the implanted medical device and further enabling patient interaction with the external device for performing event prioritization;

b. the patient monitoring system being configured to provide event prioritization for categorizing the detected cardiac events into one of at least two priority levels, the external device being configured to transmit a priority level to the equipment at the remote location; and

,

c. the equipment at the remote location being configured to receive data communicated from the external device including the identified priority level of the detected cardiac event, the equipment further configured for operating contingently upon the priority level received, wherein operating contingently includes i) responding to a first priority level event types by substantially immediately issuing notification to a medical professional; and

ii) responding to second priority level event types without providing substantially immediate notification thereof.

2. The cardiac monitoring system according to claim 1 wherein the priority level is transmitted from the external device as an event tag.

3. The cardiac monitoring system according to claim 1 wherein the priority level is transmitted from the external device as a message header.

4. The cardiac monitoring system according to claim 1 wherein the implanted device is configured to perform the event prioritization.

5. The cardiac monitoring system according to claim 1 wherein the external device is configured to perform the event prioritization.

6. The cardiac monitoring system according to claim 1 wherein the equipment at the remote location is configured to perform the event prioritization.

7. The cardiac monitoring system according to claim 1 wherein the external device is further configured for operating upon the signal data and generating at least one event tag.

8. The cardiac monitoring system according to claim 1 wherein the external device is further configured for allowing the patient to operate buttons of the external device to generate at least one event tag.

9. The cardiac monitoring system according to claim 1 wherein the remote location is a remotely located central station which is further configured providing a selected priority operation which is to alarm a medical professional that an urgent priority event has occurred.

10. The cardiac monitoring system according to claim 1 wherein the remote location is a remotely located device of a medical professional.

11. The cardiac monitoring system according to claim 1 wherein the urgent event is related to an event associated with a major cardiac event which is an acute myocardial infarction.

12. The cardiac monitoring system according to claim 2 wherein the external device is configured to allow for the event tag to include at least one selected from the group of a voice and text message which is supplied by the patient using controls on the external device.

13. The cardiac monitoring system according to claim 2 wherein the event tag can be selected by the patient from a list of preset event tags using controls on the external device.

14. The cardiac monitoring system according to claim 13 wherein event tags may include at least one of the group consisting of chest pain, patient panic, and panic.

15. The cardiac monitoring system according to claim 1 wherein the two priority levels are urgent and non-urgent.

16. The cardiac monitoring system according to claim 1 wherein at least one type of event actuates the external device for recording an audio signal by the patient which is sent with the data to the external equipment at the remote location.

17. The cardiac monitoring system according to claim 1 in which the signal data is electrical data related to cardiac activity.

18. The cardiac monitoring system according to claim 1 in which responding to first priority level event types is done contingently based upon operations defined for the event type.
