A new technique of ECG analysis was proposed to study the properties of polymorphic ventricular arrhythmias, which are life-dangerous disorders of the heart activity. The technique of data processing maps an ECG fragment onto two real indices. As result, new detailed quantitative description of polymorphic ECGs was introduced. Our observations let us to conclude that the new technique of ECG processing provides the information that supplements traditional visual ECG analysis. The estimates of ECG variation in this study reveal some unexpected details of ventricular arrhythmia dynamics, which probably will be useful for diagnostics of heart disorders.
