To our knowledge, seven articles have been published that report animal experiments of intramyocardial electrogram (IMEG) rejection monitoring on the basis of a decline of the QRS-complex amplitude [17]. This work from Everett and associates is the eighth article on this subject. All authors, except for Avitall and associates [2], who only used one bipolar ring electrode for recording of the IMEG, could find a correlation between alterations of the IMEG amplitude and the histologic findings of endomyocardial biopsy specimens, proving a sensitivity between 89% and 100% and a specificity between 77% and 90% in comparison with biopsy histology.
Three reasons could be identified for the decline of the IMEG amplitude during rejection episodes: (1) a reduced slew rate, (2) a diminished amplitude,
