ECG LEAD MISPLACEMENT DETECTION AND CORRECTION
First Claim
1. A physiological parameter analysis system (10) that detects ECG electrode wire misplacement, comprising:
- a transformation component (32) that transforms original ECG information and combinations thereof from a first ECG lead system to a second ECG lead system;
an inverse transformation component (34) that derives ECG information in the first ECG lead system from the transformed ECG information and the combinations thereof; and
an analysis component (38) that determines a correct ECG lead configuration in the first ECG lead system from among the original ECG information and the combinations thereof based on the derived ECG information.

Abstract
A physiological parameter analysis system (10) detects ECG electrode wire misplacement. The system (10) includes a transformation component (32) that transforms original ECG information and combinations thereof from a first ECG lead system to a second ECG lead system and an inverse transformation component (34) that derives ECG information in the first ECG lead system from the transformed ECG information and the combinations thereof. The system (10) further includes an analysis component (38) that determines a correct ECG lead configuration in the first ECG lead system from among the original ECG information and the combinations thereof based on the derived ECG information.

13. A method that detects ECG electrode misplacement, comprising:
-
obtaining first ECG information associated with a first ECG lead system; generating additional ECG information from the first ECG information with a plurality of combinations of electrode leads reversed; transforming the first ECG information and the plurality of additional ECG information to a second ECG lead system; deriving ECG information in the first ECG lead system from the transformed first and additional ECG information in the second lead system; analyzing the obtained first ECG information and the generated second ECG information with the derived first and additional ECG information; and determining whether a one of the obtained first and additional generated ECG information is correct ECG information based on the analysis. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. An ECG system, comprising:
-
a plurality of leads of a first lead system which are adapted to be connect with electrodes positioned on a subject and an electrocardiograph; an electrical signal analysis component which receives ECG information from the electrocardiograph representing output signals from the electrodes with an actual lead connection, the electrical signal analysis component being programmed to; a) transform the received ECG information into a second lead system, preferably the EASI lead system, and from the second lead system back to the first lead system; b) compare the received ECG information and the transformed back ECG information to determine a deviation therebetween; c) alter the ECG information to simulate a first pair of the leads being reversed; d) transform the altered ECG information into the second lead system and from the second lead system back to the first lead system; e) compare the altered ECG information with the transformed back ECG information to determine a deviation therebetween; f) repeat steps (c)-(e) to simulate each of a plurality of difference pairs of leads being reversed; g) analyze the deviations to determine if the received ECG information deviation is the smallest; and h) if the deviation for the received ECG information is not the smallest, indicate that leads have been misplaced. - View Dependent Claims (23)
