According to the present invention there is provided a cardiac diagnosis instrument including an elongated housing, diagnosis electronics accommodated within the housing and two pick-up electrodes mounted on one long side of the housing close to the front and rear ends of the instrument and electrically connected to the diagnosis electronics, a voltage source within the housing, a flat thin graphic display unit which extends along one side for a substantial part of the length of the housing on the opposite side to that on which the pick-up electrodes are located, an on-off switch, said graphic display unit and said on-off switch being electrically connected to the diagnosis electronics, said diagnosis electronics including evaluation electronics and actuation electronics for the graphic display unit, said housing having a tubular shape somewhat like that of a fountain pen, and by placing the housing on a region of the body of a patient, the pick-up electrodes may be pressed into contact with the skin of the patient and thus the frequency of the heart beat, an electrocardiogram (ECG), the QRS complex of an ECG, an electroencephalogram (EEG) or the like may be investigated through the medium of the pick-up electrodes. Preferably one of the pick-up electrodes is in the form of a holding clip starting from one end of the housing.
