ABSTRACT:
A pacemaker training aid for use in explaining the conduction system of the heart and the therapy provided by the use of a pacemaker, utilizes an illustration of the heart having lights associated therewith to show the sequence of transmission of command signals that normally cause proper action of heart chambers; the sequence of transmission of command signals usually present during improper or abnormal operation of the heart; and the effect of a pacemaker on such irregularities.
The lights are mounted at various predetermined locations on or behind the illustration in order to simulate the location of various physiological entities; the illustration is usually in the form of a color transparency. A means for controlling the sequence of illumination is provided. The sequence is determined by the normal or irregular cardiac condition which it is desired to illustrate. The placement of a pacemaker and its effect on the cardiac condition or the operation of the heart may also be illustrated, by use of a dummy pacemaker and electrode which can be attached to the training aid during the training session and an illumination sequence control which illustrates the pacemaker's effect on the heart's operation.
