Abstract :
Telemetric recording and subsequent analysis of intramyocardial electrograms offer a noninvasive method for patient monitoring after heart transplantation. Decreasing electrical activity indicates both episodes of rejection and infection. Analysis of the duration of the ventricular evoked response recorded during pacing reveals a significant increase of this parameter only during infection. In many cases, this additional information can be used to differentiate between the two pathological effects and to enhance the specificity of the method
