1. A method for medical monitoring of a patient to obtain a plurality of different physiological signal data from a common electrode set, said common electrode set having four extremity electrodes and up to six additional electrodes, wherein said method comprises the steps of:
- attaching selected electrodes of the common set to the patient in a manner to obtain up to 5 lead EKG signal data using an electrode selection made from the extremity electrodes and at least one additional electrode;
attaching at least one of the remaining additional electrodes of the common set to the patient in a manner suitable for obtaining EEG signal data or IKG signal data, the attachment of the common electrode set to the patient simultaneously generating a plurality of different physiological and signal data in the common electrode set, the electrodes of the common set being connected to a selection switch (K);
operating the selection switch (K) for selecting one of;
the selected electrodes of the common set or the remaining additional electrodes of the common set; and
obtaining from the physiological signal data in the electrodes selected by operating the selection switch, one of up to 5 lead EKG signal data or one of EEG and IKG signal data.

Abstract
The invention relates to a method and a system for a medical monitoring system, in which method the functions of a patient are measured, and the change in the electric activity of the patient are observed. In the method, the electrocardiogram (EKG), electroencephalogram (EEG), and the impedance cardiograph signal (IKG) are being measured with one piece of measuring equipment.

8. A system for medical monitoring apparatus comprising:
-
a common electrode set including four patient extremity electrodes adapted to be attached to a patient (P) and up to six additional electrodes adapted to be attached to the patient (P), one of said additional electrodes being includable with said extremity electrodes in a first electrode set for obtaining EKG signal data and the remaining additional electrodes being includable in a second electrode set for obtaining EEG or IKG signal data; signal conductors connected to each of said electrodes in the common electrode set; a common measurement device comprising electrocardiographic (EKG) measuring equipment, electroencephalographic (EEG) measuring equipment and impedance cardiographic (IKG) measuring equipment; and a selector switch (K) interposed between said conductors connected to the common electrode set and said measurement device for selecting the measuring equipment to receive physiological data from the first or second electrode set such that when the selector switch (K) is in a first position EKG signal data from the first electrode set is sent to the electrocardiographic measuring equipment, when the selector switch (K) is in a second position the additional electrodes provide a selected one of EEG signal data from the second electrode set that is sent to said electroencephalographic (EEG) measuring equipment and when the selector switch (K) is in a third position IKG signal data from the second electrode set is sent to said impedance cardiographic (IKG) measuring equipment. - View Dependent Claims (9, 10)
