Abstract
Apparatus for inspecting the electrical stimulation of a patients' heart. The apparatus includes a stimulation device in which electrical stimulating wave is generated by an electrical stimulation wave generating device for effecting pacing of a patients' heart in accordance with an externally set stimulation pattern impressed upon the wave and applied to the heart through a catheter, wherein intracardiac electrocardiogram signals are induced, amplified, and recorded on a recorder which is annexed to the stimulation device. The recorder is designed to commence the recording operation in response to a recording start signal in advance of the generation of the final electrical stimulation wave, and to stop the recording operation in response to the intracardiac electrocardiogram signal generated for the first time after the generation of the final electrical stimulation wave. During the operation, waveforms of the final stimulation signal and the intracardiac electrocardiogram signal are recorded and the characters representing the stimulation pattern are printed.
