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.

Abstract: A process for sensing and analyzing electrical activity of the human heart includes the use of a set of electrodes for a first lead system and an ECG monitor design for use with a second lead system that is different from the first lead system. Output signals from the first lead system electrodes are connected to first, second and third channel inputs for the ECG monitor. The input signals to the ECG monitor are linearly transformed to output first, second and third ECG channels which are consistent with standard output for the first lead system. In linearly transforming the inputted signals to the ECG monitor, differences between the first lead system electrodes and the ECG monitor are manipulated either before the output signals from the first lead system electrodes are fed to the channel inputs for the ECG monitor, or after the ECG monitor has formed channels.

Abstract: A method of sensing and analyzing electrical activity of the human heart comprises the sensing of voltage signals generated by the heart between four electrodes (E, A, S and I) located at key positions on the surface of a subject's body. The E electrode is attachable to the anterior midline of the subject body at a level selected from the group consisting of the fourth rib interspace and the fifth rib interspace. The A and I electrodes are attachable to the subject's body on opposed sides of the anterior midline below the level of the E electrode but high enough so they are positioned over the subject's ribs or intercostal spaces. The S electrode is positioned over the subject's manubrium sterni. Signal processing means combines and scales the voltage signals to produce xyz vectorcardiographic signals, electrocardiographic signals corresponding to the lead signals of a 12-lead electrocardiograph, or both.
