Abstract

A device, system and method for obtaining a 12 lead electrocardiogram (ECG) from measurements obtained with 3 electrodes in some embodiments (it should be noted that some separate embodiments of the present invention relate to such measurements with 4 electrodes). Optionally and preferably, the device, system and method of the present invention may be easily and accurately operated by a layperson.

Claims

1. A device for performing a 12 lead ECG on a body of a subject, comprising an electrode array, said array comprising only three electrodes, and a housing, wherein one electrode of said array is located on a lower surface of said housing and wherein a plurality of electrodes of said array is located on an upper surface of said housing, wherein at least one electrode records a plurality of measurements at a plurality of different locations on the body of the subject, wherein a plurality of electrodes is in contact with a lower torso or leg of the body of the subject, while said at least one electrode is sequentially in contact with said plurality of different locations on an upper torso of the body of the subject corresponding to V1 to V6, wherein each electrode is in contact with a different part of the body of the subject and wherein said plurality of electrodes is in contact with a surface of the body of the subject simultaneously or substantially simultaneously with said at least one electrode being in sequential contact with said plurality of different locations.

26. A system for performing a 12 lead ECG on a body of a subject, comprising a device according to claim 1 and further comprising:

A processor for executing at least one instruction for processing said measurements, wherein said processor is comprised in a computer selected from the group consisting of a cellular telephone, a laptop computer, a smartphone, a PDA and a pager and wherein said computer is separated from said device.

30. The system of claim 26, further comprising a remote location for analyzing said measurements.

31. The system of claim 30, wherein said remote location features medical personnel.

32. The system of claim 31, further comprising a dynamic reference electrode between a plurality of electrodes is calculated in relation to said reference electrode, sequentially or simultaneously.

33. The system of claim 32, wherein each of said plurality of electrodes functions as a dynamic reference electrode in turn for each limb lead calculation.

34. The system of claim 33, further comprising a calculator for determining an arithmetic calculated value as a reference.

35. The system claim 34, further comprising signal acquisition component for acquiring the signals from the electrodes.

36. The system of claim 35, further comprising a signal amplification component.

37. The system of claim 36, further comprising a noise reduction component.

38. The system of claim 37, further comprising a data transmission component.

39. The system of claim 38, further comprising a memory component.

40. The system of claim 39, wherein said memory component stores coordinates for at least one recording location on the body, wherein said coordinates relate to V1 to V6 locations.

42. The system of claim 40 wherein said memory component further stores an image of the body of the subject and said coordinates are marked on said image.

43. The system of claim 39, wherein said memory stores medical information of the subject.

44. The system of claim 43, further comprising a navigation system for locating said plurality of different recording locations.

45. The system of claim 44, wherein said navigation system includes a visual display.

46. The system of claim 45, wherein said navigation system includes an audio display.

47. The system of claim 44, wherein said navigation system includes a vibrating component.

48. The system of claim 47, wherein one or more of said visual display, audio display or vibrating component alerts a user as to at least one recording location.
