Abstract

A system for cardiac monitoring of an individual. The system includes a garment having a plurality of nanostructured textile electrodes integrated therein, the electrodes arranged on the garment to record data for an ECG of the individual; a first controller electrically coupled to the plurality of electrodes, the controller including a wireless transmitter, the first controller being configured to collect the recorded data for the ECG from the plurality of electrodes and to cause the wireless transmitter to wirelessly transmit the recorded data; and a wireless receiving station including a wireless receiver and a second controller, the second controller configured to cause the wireless receiver to receive the recorded data transmitted by the wireless transmitter, analyze the recorded data for the ECG, analyze the recorded data, identify an abnormality in the ECG, and generate an alert if an abnormality in the ECG is identified.

Claims

1. A system for cardiac monitoring of an individual, comprising:

a garment having a plurality of nanostructured textile electrodes integrated therein, the electrodes being arranged on the garment to record data for an ECG of the individual;

a first controller electrically coupled to the plurality of electrodes, the controller including a wireless transmitter, the first controller being configured to collect the recorded data for the ECG from the plurality of electrodes and to cause the wireless transmitter to wirelessly transmit the recorded data; and

a wireless receiving station comprising a wireless receiver and a second controller, the second controller configured to cause the wireless receiver to receive the recorded data transmitted by the wireless transmitter and to analyze the recorded data for the ECG,

the second controller further configured to

analyze the recorded data,

identify an abnormality in the ECG, and

generate an alert if an abnormality in the ECG is identified.

2. The system of claim 1, wherein the abnormality in the ECG comprises an inverted T-wave.

3. The system of claim 1, wherein the plurality of nanostructured textile electrodes comprises a plurality of measured ECG leads.

4. The system of claim 3, wherein the plurality of measured ECG leads include leads I, II, V1, and V5-V6 of a 12-lead ECG.

5. The system of claim 4, wherein at least one lead of a 12-lead ECG is algebraically derived from at least one of the plurality of measured ECG leads.

6. The system of claim 1, wherein the first controller is electrically coupled to the plurality of nanostructured textile electrodes by fabric threads comprising silver.

7. The system of claim 1, wherein the plurality of nanostructured textile electrodes comprises dry electrodes.

8. The system of claim 1, wherein the first controller is connected to the individual.

9. The system of claim 1, wherein the wireless transmitter and the wireless receiver communicate using a ZigBee protocol.

10. The system of claim 1, wherein the alert is sent to one or more medical personnel.

11. The system of claim 1, wherein the plurality of nanostructured textile electrodes are integrated into fabric of the garment.

12. The system of claim 1, wherein the garment comprises a stretchable undergarment.

13. A system for cardiac monitoring of a group of individuals, comprising

a plurality of wearable monitoring units, each wearable monitoring unit comprising

a garment having a plurality of nanostructured textile electrodes integrated therein, the electrodes being arranged on the garment to record data for an ECG of the individual;

a first controller electrically coupled to the plurality of electrodes, the controller including a wireless transmitter, the first controller being configured to collect the recorded data for the ECG from the plurality of electrodes and to cause the wireless transmitter to wirelessly transmit the recorded data; and

at least one wireless receiving station comprising a wireless receiver and a second controller, the second controller configured to cause the wireless receiver to receive the recorded data transmitted by the wireless transmitter and to analyze the recorded data for the ECG,

the second controller further configured to

analyze the recorded data,

identify an abnormality in the ECG, and

generate an alert if an abnormality in the ECG is identified.

14. The system of claim 13, further comprising a second wireless receiving station, wherein each of the plurality of wearable monitoring units communicates with only one wireless receiving station.

15. The system of claim 13, wherein the abnormality in the ECG comprises an inverted T-wave.
