ABSTRACT:
The apparatus for recording an electrocardiogram capable of displaying a change of spike intervals of adjacent QRS groups among a plurality of QRS groups of an electrocardiographic wave, the apparatus capable of displaying a time change of an electric potential with heart pulsations, the QRS groups showing an electric potential at a start of a ventricular systole includes a first memory unit for storing a measured electrocardiographic wave proportional to a predetermined time period, a unit for detecting a reference point of each R wave of the QRS groups in the electrocardiographic wave stored in the memory unit, a unit for displaying the electrocardiographic wave stored in the memory unit, and a control unit for controlling the display unit so that a reference point of one of the QRS groups in the electrocardiographic wave is displayed at a predetermined position on displaying unit, the control unit being capable of shifting the QRS groups in a time scale while the electrocardiographic wave is displayed on the display unit.
