Abstract

Disclosed is a means and method to decrease mortality and morbidity of patients who regularly undergo either hemodialysis (typically) at a hospital or who undergo peritoneal dialysis at home. The present invention utilizes an implantable system that can detect early signs of a heart attack by noting changes in the electrogram signal from an electrode placed near the apex of the right ventricle of the patient'"'"'s heart. What is specifically noted from the electrogram for the early detection of a heart attack is a shift in the ST segment compared to a baseline level of the ST segment that was placed in the implanted device'"'"'s memory at an earlier time. The implanted system is also in contact with an externally located alarm means that also can alert the patient if a heart attack occurs.

Claims

1. A method for providing an alarm signal to alert a dialysis patient that he or she is having a heart attack, the method including the following steps:

a) determining if the patient is a dialysis patient who has been connected to a system that performs dialysis;

b) implanting into the patient a system for early warning of a heart attack by means of noting an ST segment shift in that patient'"'"'s electrogram;

c) sounding an alarm from within the implanted system to warn the patient that he or she is having a heart attack.

2. The method of claim 1 including the additional step of having an external alarm system in close enough proximity to the dialysis patient so that it would receive a signal from the implanted system indicating that a heart attack has been detected.

3. The method of claim 2 including the additional step of having the external system provide an audio alarm when a heart attack is detected by the implanted system, the audio alarm being able to be detected by the dialysis patient who is having a heart attack.

4. The method of claim 2 including the additional step of having the external alarm system being capable of communicating with a remotely located diagnostic center, the diagnostic center having a medical practitioner who would have voice contact with the patient after the implanted system has indicated that a heart attack has been detected.

5. The method of claim 1 including the additional step of determining if the patient has diabetes.

6. The method of claim 1 including the additional step of determining if the patient has had a prior heart attack.

7. The method of claim 1 including the additional step of determining if the patient has diabetes and has had a prior heart attack.

8. The method of claim 1 including the additional step of determining if the patient has an implanted pacemaker of defibrillator.
