This paper introduces the preamplifier of ventricular late potentials, and give out testing instance and performance parameters, experiment results show that this preamplifier is viable and reliable.
Objective:To validate the feasibility and value of myocardial performance index (MPI) for assessing ventricular function in patients with functionally single ventricle.
