Apparatus for inspecting an electrically stimulated heart
First Claim
1. Apparatus for inspecting the electrical stimulation of a patient'"'"'s heart, said apparatus including a stimulation means wherein an electrical stimulating wave is generated by an electrical stimulation wave generating means so to effect pacing of said heart in accordance with an externally set stimulating pattern impressed upon said wave and applied to said heart through a catheter, wherein intracardiac recorded on a recorder which is annexed to said stimulation means, said apparatus comprising:
- (a) a final stimulation signal generating means for generating a final stimulation signal at a timing corresponding to a final electrical stimulation wave;
(b) a stimulation pattern generating means for generating a stimulation pattern representative of said stimulation pattern;
(c) a recording start signal generating means for generating a recording start signal for starting said recorder in advance of said generation of said final electrical stimulating wave;
(d) detecting said intracardiac electrocardiogram signal generated for the first time after said generation of said final electrical stimulation wave, and for generating a recording stop signal after the detection of said intracardiac electrocardiogram signal;
(e) a recording signal generating means for generating recording signals in accordance with which, the waveforms of said final stimulation signal and said intracardiac electrocardiogram signal are recorded, and the characters corresponding to said stimulation pattern are printed by said recorder; and
(f) a recording control means for starting the recording operation of said recorder in response to said recording start signal and stopping the recording operation in response to a said recording stop signal.

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.
