Abstract: The present invention relates to a method for eliminating interference due to artefacts of a person's movement or having a non-biological origin such as various electrical interference or noises generated by appliances. To this end, pulses of an electrical current are recorded wherein said pulses are function of a phase component of the derma electrical activity. The incoming time of a first time-derivative pulse is then determined using the logarithm of the numerical value of a current that is recorded at the moment when the value of a second derivative exceeds a threshold value. The form of the pulse is further analysed and, when parameters of this form correspond to given criteria, said pulse is related to the phase component pulses. When the parameters of this form do not correspond to the given criteria, the pulse is related to the artefacts. The analysis of pulse form may be performed using instruments or programmes.

Abstract: In order to sense weak electromagnetic fields, in particular bioelectric fields caused by currents in nerve fibres, an electromagnetic grid (1) is created made up of electromagnetic force lines that cross each other in a plane, are periodically repeated and successively generated in time, so that the bioelectric fields cause changes in the electromagnetic force lines. The bioelectric fields are sensed by means of an outer stimulus (16) applied to a human or animal body through the sense organs (17), for example the sense of touch, and are transmitted by nerve bundles (20) to the brain (21). The fields obtained with the electromagnetic grid are transmitted to a coding unit (14) that retransmits the signals, together with a code corresponding to the outer stimulus, to a computer (22) that evaluates and stores the signals.

Abstract: This invention is systems and methods to examine heart tissue morphology using a pair of electrodes (38), at least one of which is located in contact with heart tissue (12). The systems and methods transmit electrical current in a path through the contacted heart tissue (12) between the pair of the electrodes to derive a tissue electrical characteristic based, at least in part, upon sensing the impedance of the tissue lying in the path. The system and methods also sense with at least one of the electrodes the timing of local depolarization events in the contacted heart tissue. The systems and methods make possible the use of multiple endocardial electrodes (30) for taking multiple measurements of the electrical characteristics of heart tissue. Multiplexing can be used to facilitate data processing. The systems and methods also make possible the identification of regions of low relative electrical characteristics, indicative of infarcted tissue, without invasive surgical techniques.
