1. A method of cardiac monitoring and angina pectoris treatment of a patient by using a cardiac condition detector and a stimulating electrode, comprising the steps of:
- placing said cardiac condition detector at a recording site adjacent said patient or in said patient;
implanting said stimulating electrode adjacent a spinal cord or in said spinal cord of said patient;
receiving an indicia of the condition of a heart muscle of said patient through said detector;
processing said indicia to detect an occurrence of an ischemic event;
generating an indication detectable by said patient of said occurrence of said ischemic event in response to said processing;
generating electrical pulses suitable for stimulating said spinal cord to reduce angina; and
gating said pulses to said stimulating electrode, whereby said angina pectoris is reduced while the patient is given an indication of an ischemic event that otherwise would be indicated by said angina pectoris.

Abstract
Techniques for cardiac monitoring and angina pectoris treatment using a cardiac condition detector and stimulating electrode. The detector and electrode are implanted. Angina is relieved by transmitting electrical pulses to the stimulating electrode while the patient is giving an indication of an ischemic event that otherwise would be indicated by the angina.

13. Apparatus for cardiac monitoring and angina pectoris treatment of a patient comprising:
-
a cardiac condition detector adapted to be placed at a recording site adjacent said patient or in said patient for generating an indicia of the condition of a heart muscle of said patient; a stimulating electrode adapted to be implanted adjacent a spinal cord or in said spinal cord of said patient; means for processing said indicia to detect an occurrence of an ischemic event; means for generating an indication detectable by said patient of an occurrence of said ischemic event in response to said processing; means for generating electrical pulses suitable for stimulating said spinal cord to reduce angina; and means for gating said pulses to said stimulating electrode, whereby said angina pectoris is reduced while the patient is given an indication of an ischemic event that otherwise would be indicated by said angina pectoris. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
