Abstract
An ECG monitoring system for ambulatory patients includes a reusable battery-powered ECG monitor with an electrode attached to a patient for receiving ECG signals. A processor analyzes the received ECG signals for predefined arrhythmia. If an arrhythmia is detected, a wireless transceiver in the ECG monitor transmits the event information and an ECG strip to a cellphone handset. The cellphone handset automatically relays the event information and ECG strip to a monitoring center for further diagnosis and necessary intervention. The ECG monitor sends notifications to the cellphone handset whenever the status of the monitor changes. The cellphone handset forwards status notifications to which a patient response has not been received to the monitoring center, as well as status notifications generated by the cellphone handset.

3. A wireless cardiac monitoring system comprising:
-
a battery powered ECG monitor adapted to receive cardiac signals from an electrode attached to a patient, the ECG monitor including a transceiver for wirelessly transmitting ECG signal data, the ECG monitor further including a status notifier, coupled to the transceiver, for transmitting a status notification when a status of the ECG monitor changes; and a cellphone handset including cellphone electronics operable for communication over a cellular network and a transceiver for wirelessly receiving ECG signal data or status notifications from the ECG monitor and a controller operable to cause the cellphone electronics to send ECG signal data received from the ECG monitor to a monitoring center over the cellular network, wherein the controller is further operable to respond to a status notification from the ECG monitor by at least one of a) bringing a status notification to the attention of the patient with the cellphone handset, or b) sending the status notification to the monitoring center over the cellular network, wherein the controller is further operable to delay sending a given status notification to the monitoring center to allow time for receipt of a rectifying status notification. - View Dependent Claims (4, 5, 6, 7)

12. A wireless cardiac monitoring system comprising:
-
a battery powered ECG monitor adapted to receive cardiac signals from an electrode attached to a patient, the ECG monitor including a transceiver for wirelessly transmitting ECG signal data, the ECG monitor further including a status notifier, coupled to the transceiver, for transmitting a status notification when a status of the ECG monitor changes; and a cellphone handset including cellphone electronics operable for communication over a cellular network and a transceiver for wirelessly receiving ECG signal data or status notifications from the ECG monitor and a controller operable to cause the cellphone electronics to send ECG signal data received from the ECG monitor to a monitoring center over the cellular network, wherein the controller is further operable to respond to a status notification from the ECG monitor by at least one of a) bringing a status notification to the attention of the patient with the cellphone handset, or b) sending the status notification to the monitoring center over the cellular network, wherein a status notification is brought to the attention of the patient with at least one of a display of the cellphone, a tone produced by the cellphone, or a voice prompt issued by the cellphone, and further wherein, when a change in status is brought to the attention of the patient, the patient is given the option of responding immediately to alter the new status, or deferring a response to the status notification until a later time.
