Abstract

A machine-implemented method including obtaining physiological signal data for a living being and performing a first analysis of the physiological signal data at a processing device local to the living being and remote from a central processing device. The method further includes transmitting from the processing device data associated with the analysis to the central processing device and performing at the central processing device a second analysis of the data associated with the first analysis. The method further includes displaying the data associated with the second analysis. The method can also include interaction between the processing device local to the living being and the central processing device. The method can also include distributing monitoring and analysis between an ambulatory and a centralized subsystem.

Claims

1-29. -29. (canceled)

30. A system for monitoring a patient, the system comprising:

a monitoring device configured to communicate with at least one sensor coupled to a patient, the monitoring device configured to receive physiologic data about the patient from the at least one sensor;

a memory configured to store the received physiologic data; and

a wireless transceiver coupled to the monitoring device and configured to (1) transmit to a central processing device, a subset of the received physiologic data, (2) receive from the central processing device a signal generated based on the central processing device analyzing the subset of the received physiologic data according to a first technique and thereby identifying a health-related anomaly, and (3) transmit, in response to receiving the signal, a portion of the received physiologic data to the central processing device for analysis by the central processing device according to a second technique that validates the health-related anomaly identified by the first technique.

31. The system of claim 30, wherein the health-related anomaly is an arrhythmia event.

32. The system of claim 31, wherein the arrhythmia event is an atrial fibrillation (AF) event.

33. The system of claim 30, wherein the at least one sensor is configured to be coupled to the patient to generate physiologic data about the patient.

34. The system of claim 30, wherein the signal from the central processing device is a request for the portion of the received physiologic data.

35. The system of claim 30, wherein the physiologic data comprise ECG data.

36. The system of claim 35, wherein the subset of the received physiologic data comprises fiducial points of a QRS complex.

37. The system of claim 30, wherein the wireless transceiver is further configured to send the signal identifying the health-related anomaly over a cellular network.

38. The system of claim 30, wherein the memory is configured to store the physiologic data in a circular buffer.

39. The system of claim 30, wherein the monitoring device is configured to wirelessly receive the physiologic data from the at least one sensor.

40. A method for monitoring a patient, the method comprising:

receiving physiologic data about a patient from at least one sensor coupled to the patient;

storing the received physiologic data in a memory;

transmitting, to a central processing device, a subset of the received physiologic data;

receiving, from the central processing device, a signal generated based on the central processing device analyzing the subset of the received physiologic data according to a first technique and thereby identifying a health-related anomaly; and

transmitting, in response to receiving the signal, a portion of the received physiologic data to the central processing device for analysis by the central processing device according to a second technique that validates the health-related anomaly identified by the first technique.

41. The method of claim 40, wherein the health-related anomaly is an arrhythmia event.

42. The method of claim 41, wherein the arrhythmia event is an atrial fibrillation (AF) event.

43. The method of claim 40, wherein a monitoring device receives the physiologic data, and wherein the monitoring device is communicatively coupled to the at least one sensor coupled to the patient.

44. The method of claim 40, wherein the signal from the central processing device is a request for the portion of the received physiologic data.

45. The method of claim 40, wherein the physiologic data comprises ECG data.

46. The method of claim 45, wherein the subset of the received physiologic data comprises fiducial points of a QRS complex.

47. The method of claim 40, wherein transmitting, to the central processing device, the subset of the received physiologic data comprises transmitting, via a wireless transceiver, the subset of the received physiologic data over a cellular network.

48. The method of claim 40, wherein the memory stores the physiologic data in a circular buffer.

49. The method of claim 40, wherein the physiologic data is received wirelessly from the at least one sensor.
