Abstract

An ECG monitoring system for ambulatory patients includes a battery-powered ECG monitor which attaches to a patient to receive patient electrical signals. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. A wireless transceiver in the ECG monitor transmits the processed ECG signals to a cellphone handset. The battery of the monitor is recharged when the monitor is properly positioned in a charging dock, during which time the ECG signals are sent to the cellphone handset. Preferably the cellphone handset is recharged by the charging dock at the same time. At the conclusion of recharging and data transfer the monitor performs a self-test. A light on the charging dock is illuminated if any of the operations performed while the monitor is docked is unsuccessful.

Claims

1. An electrocardiogram (ECG) monitoring system for cardiac monitoring of an ambulatory patient comprising:

a battery powered ECG monitor adapted to receive cardiac signals from an electrode attached to a patient, the ECG monitor further including an ECG signal processor operable to detect an arrhythmia from the cardiac signals, a memory for storing an archive of processed ECG signals, and a transceiver for wirelessly transmitting ECG signal data corresponding to the arrhythmia;

a cellphone handset including cellphone electronics operable for communication over a cellular network and a transceiver for wirelessly receiving ECG signal data and archive data from the ECG monitor; and

a charging dock to which the ECG monitor is coupled when not receiving cardiac signals from a patient, the charging dock being operable to recharge the battery of the battery powered ECG monitor,

wherein the ECG monitor is further operable to sense a coupling to the charging dock and to sense an engagement to the electrode, and further wherein the ECG monitor is operable to wirelessly transmit the archive of ECG signals stored in the memory to the cellphone handset responsive to the sensed coupling and to wirelessly transmit the ECG signal data to the cellphone handset responsive to the sensed engagement.

2. The ECG monitoring system of claim 1, wherein the cellphone handset is further responsive to the receipt of the archive of ECG signals from the ECG monitor for sending the archive of ECG signals to a monitoring center over the cellular network.

3. The ECG monitoring system of claim 1, wherein the ECG monitor is further operable, following transmission of the archive of ECG signals stored in the memory to the cellphone handset, to clear the stored archive of ECG signals from the memory.

4. The ECG monitoring system of claim 1, wherein the charging dock is further operable to recharge the cellphone handset while a battery of the battery powered ECG monitor is being recharged.

5. The ECG monitoring system of claim 1, wherein the ECG monitor further includes a processor for automatically performing a self-test of the ECG monitor when the ECG monitor has been coupled to the charging dock for recharging.

6. The ECG monitoring system of claim 5, wherein the self-test is performed at a conclusion of recharging by the charging dock.

7. The ECG monitoring system of claim 1, wherein the charging dock is operable to recharge a battery of the battery powered ECG monitor after verification that the ECG monitor has been properly coupled to the charging dock.

8. The ECG monitoring system of claim 1, wherein the ECG monitor further includes a plurality of electrical contacts coupled to the battery;

and

wherein the charging dock further includes a compartment into which the ECG monitor is located for recharging;

a plurality of contacts located in the compartment which engages ECG monitor contacts for recharging when the ECG monitor is properly located in the compartment; and

a lid which must be closed during recharge of a battery of the ECG monitor.

9. The ECG monitoring system of claim 8, wherein the ECG monitor is keyed for proper placement in the compartment;

and

wherein the compartment is correspondingly keyed to engage the keying of the ECG monitor when the ECG monitor is properly placed in the compartment.

10. The ECG monitoring system of claim 8, further comprising circuitry adapted to verify that electrical contacts of the ECG monitor are properly engaged with the contacts located in the compartment of the charging dock.

11. The ECG monitoring system of claim 10, wherein electrical contacts of the ECG monitor are properly engaged with the contacts located in the compartment only when the lid is closed.

12. The ECG monitoring system of claim 1, wherein the charging dock further comprises a light which is illuminated while the battery of the ECG monitor is being recharged.

13. The ECG monitoring system of claim 12, wherein illumination of the light is changed when recharge of the battery of the ECG monitor is unsuccessful.

14. The ECG monitoring system of claim 13, wherein the ECG monitor is further operable to perform a self-test at a conclusion of recharging;

wherein a illumination of the light is changed when a result of the self-test is undesirable.

15. The ECG monitoring system of claim 12,

wherein a illumination of the light is changed when the transmitted archive of ECG signals is not properly received.

16. The ECG monitoring system of claim 1, wherein ECG monitor further comprises a plurality of electrical contacts coupled to the ECG signal processor;

and

wherein the charging dock is further operable to apply test signals to the electrical contacts for testing of the ECG signal processor of the ECG monitor.

17. The ECG monitoring system of claim 1, further comprising a second battery powered ECG monitor which is also be recharged by the charging dock,

wherein the second battery powered ECG monitor receives cardiac signals from the patient while the first ECG monitor is being recharged by the charging dock.
