Abstract
A phase singularity identification system includes: a signal reception unit for receiving a single activity electrogram signal measured through a single-electrode catheter at a particular point of a cardiac muscle cell; a phase calculation unit for calculating a phase from the received single activity electrogram signal; and a phase singularity identification unit for identifying through the calculated phase if the particular point of the cardiac muscle cell is a phase singularity. Accordingly, it is possible to identify the phase singularity of a rotor by using a single-electrode catheter rather than a multi-electrode catheter, thereby significantly reducing time required and costs spent in comparison with prior art, and it is possible to accurately identify the phase singularity of the rotor, thus the system can be used for a radiofrequency electrode catheter ablation procedure for cardiac arrhythmia treatment.
