Abstract
A tachycardia eliminating apparatus includes a heartbeat detector which detects heartbeats in an input heart activity signal which delivers an output heartbeat signal indicating each detected heartbeat, a tachycardia detector coupled to the output of the heartbeat detector which generates a tachycardia indication signal in response to a detected tachycardia status of a heart as reflected in the heartbeat signal, and a respiratory system stimulator coupled to the output of the tachycardia detector and generating an output respiratory system stimulation signal for stimulating a respiratory system to achieve a stimulated breathing rate, with the ratio of the detected heartbeat rate to the stimulated breathing rate corresponding to a predetermined value.
Claims14
A tachycardia eliminating apparatus comprising:
- means for obtaining a cardiac activity signal from a patient;
- cardiac status detecting means, supplied with said cardiac activity signal, for detecting a status of a cardiac system and for generating an output cardiac status signal;
- tachycardia detecting means, supplied with said output cardiac status signal, for identifying at least one of impending tachycardia and established tachycardia and for generating an output tachycardia indication signal dependent on a deviation of said output cardiac status signal from a predetermined cardiac status;
- and
- respiratory system stimulating means, supplied with said output tachycardia indication signal, for generating, in response to an indication of impending or established tachycardia, an output respiratory system stimulation signal for stimulating a respiratory system organ for producing a breathing rate corresponding to a predetermined heartbeat rate.
The tachycardia eliminating apparatus as claimed in claim I wherein said means for obtaining a cardiac activity signal comprises means for obtaining a heartbeat signal, and wherein said cardiac status detecting means comprises a heartbeat detector.
The tachycardia eliminating apparatus as claimed in claim I further comprising a ventilator, said ventilator comprising ventilator control means, supplied with said output respiratory system stimulation signal, for controlling said ventilator for producing respiration in a patient at said breathing rate corresponding to said predetermined heartbeat rate.
