New criteria for analysis of ventricular late potentials using high-resolution electrocardiography

The aim of our study is to determine a new statistical criteria for classification of patients (pts) with late potentials. The main assumption is that it is not important to know exactly the values of three Simson parameters of QRS complex vector [1,2] but it is significant to use this type of digital filter which preserve the shape of filtered signal and using new parameters for dimensioning the QRS complex the multidimensional "diagnostic vector" is calculated.
