Reliability of using tslew of intramyocardial electrogram to diagnose acute rejection after heart transplantation in rats

摘要

Objective This study aimed to evaluate the reliability of Tslew in survelliance of allograft rejection after heart transplantations in rats. Methods Forty rats underwent modified Ono ’s heterotopic heart transplantation. The autonomous IMEG and VER were recorded with epicardiac pacing leads fixed at right ventricular outflow tracts,left ventricular apex and free wall. Tslews were detected daily in these 10 syngeneic and 30 allogeneic transplants. Syngeneic transplants were sacrificed at 7th postoperative day and allogeneic transplants were sacrificed
