Intramyocardial electrograms measurements in patients after heart transplantation
<p><strong>Background:</strong> Adequate detection and treatment of acute allograft rejection is one of the most important predictors of post-transplant survival of cardiac transplant recipients. Recently, a number of novel, non-invasive tools have allowed for earlier detection and...
