Method for recognizing rejection of transplanted hearts
First Claim
1. A method of monitoring a body reaction against a heart transplanted therein, comprising steps of:
- detecting inside the body analog electrocardiac signals from a newly transplanted heart in the body;
within the body converting the analog signals to digital signals;
within the body carrying out a first differentiation of the digital signals over a continuous time period to create reference differentiated signals;
at a later time during monitoring of the heart, again detecting within the body analog electrocardiac signals from the transplanted heart;
within the body converting the analog signals to digital signals;
within the body carrying out a first differentiation of the digital signals over a continuous time period to create newly monitored differentiated signals;
within the body comparing the newly monitored differentiated signals with the reference differentiated signals to create comparison results;
recording and storing within the body the comparison results; and
at a desired time, transmitting the stored comparison results from inside the body to outside the body for use in analyzing body rejection of the transplanted heart.

Abstract
A method is disclosed for monitoring the body reaction against a heart transplant. When a heart is newly transplanted, electrocardiac signals from the transplanted heart are detected. The analog signals are converted to digital signals. A first differentiation of the digital signals is carried out over a continuous time period to create reference differentiated signals. At a later time during monitoring of the transplanted heart, analog electrocardiac signals are again detected from the transplanted heart. These analog signals are converted to digital signals. A first differentiation is carried out of these digital signals over a continuous time period to create monitored differentiated signals. The reference differentiated signals and the monitored differentiated signals are compared at least with respect to amplitude to create comparison results. All of the above operations occur within the body. These comparison results are recorded and stored for use in determining body rejection of the transplanted heart.
