Abstract

An apparatus including a chest strip comprising a plurality of precordial and limb leads for an electrocardiogram (ECG) and an ECG data recorder coupled to the chest strip, wherein the ECG data recorder configured to receive signals from the leads. An apparatus including a chest strip comprising a plurality of precordial leads positioned to correspond with desired lead placement for an electrocardiogram (ECG) and an ECG data recorder; a plurality of limb leads coupled to the chest strip, wherein the ECG data recorder is coupled to plurality of precordial leads and the plurality of limb leads and configured to receive electrocardiogram data generated by the plurality of precordial leads and the plurality of limb leads. A method including coupling a chest strip including precordial leads and a data recorder to a newborn, the data recorder configured to receive electrocardiogram data from the precordial leads; and transmitting electrocardiogram data from the data recorder.

Claims

1. An apparatus comprising:

a chest strip having dimensions suitable for a chest of a newborn and shaped to conform to anatomic positions of a newborn for a placement of precordial leads, the chest strip comprising (1) at least one landmark to aid in positioning of the chest strip on a newborn;

(2) a plurality of precordial and limb leads for an electrocardiogram (ECG); and

(3) an ECG data recorder coupled to the chest strip, wherein the ECG data recorder is configured to receive signals from the leads.

3. The apparatus of claim 1, wherein the ECG data recorder is detachable.

4. The apparatus of claim 1, wherein the limb leads are connected to the chest strip by individual wires, the wires providing an acceptable length to extend a desired limb placement.

5. The apparatus of claim 1, further comprising a plurality of electrodes, wherein respective ones of the electrodes are coupled to the plurality of leads.

6. The apparatus of claim 3, further comprising an ECG analog receiver configured to receive analog data signals from the leads and convert the analog signals to digital signals for recording by the data recorder.

2. The apparatus of 1, wherein the precordial leads are positioned relative to the at least one landmark to correspond with a desired lead placement for a newborn.

7. An apparatus comprising:

a chest strip having dimensions suitable for a chest of a newborn, the chest strip and shaped to conform to anatomic positions of a newborn for a placement of precordial leads comprising (1) at least one landmark to aid in positioning of the chest strip on a newborn;

(2) a plurality of precordial leads positioned to correspond with desired lead placement for an electrocardiogram (ECG); and

(3) an ECG data recorder;

a plurality of limb leads coupled to the chest strip,

wherein the ECG data recorder is coupled to plurality of precordial leads and the plurality of limb leads and configured to receive electrocardiogram data generated by the plurality of precordial leads and the plurality of limb leads.

8. The apparatus of claim 7, wherein the ECG data recorder is detachable from the chest strip.

9. The apparatus of claim 7, further comprising a plurality of electrodes coupled to respective ones of the plurality of precordial leads.

10. The apparatus of claim 7, wherein the chest strip further comprise an analog receiver configured to receive analog data signals from the leads and convert the analog signals to digital signals for recording by the ECG data recorder.

11. The apparatus of claim 7, wherein the ECG data recorder is configured to record digital ECG data to onboard flash memory, and to send the ECG data to a wireless transmitter.

12. A method comprising:

coupling a chest strip shaped to conform to anatomic positions of a newborn for a placement of precordial leads and comprising precordial leads and a data recorder to a newborn such that a V1 precordial lead is in a 4th intercostal space on a right sternal border and a V2 precordial lead will be in a 4th intercostal space on a left sternal border, the data recorder configured to receive electrocardiogram data from the precordial leads; and

transmitting electrocardiogram data from the data recorder.

13. The method of claim 12, wherein the chest strip further comprises a plurality of limb leads, the method further comprising coupling the plurality of limb leads to respective ones of the limbs of the newborn.

14. The method of claim 12, wherein prior to transmitting electrocardiogram data, removing the data recorder from the chest strip.

15. The method of claim 14, wherein prior to transmitting electrocardiogram data, the method comprises:

retrieving electrocardiogram data.

16. The method of claim 15, wherein retrieving electrocardiogram data is done away from a medical office or examination room.

17. The method of claim 16, wherein after retrieving electrocardiogram data, detaching the data recorder from the chest strip.

18. The method of claim 12, wherein transmitting is done wirelessly.
