Electrical excitation in the heart initiates from the sinoatrial node which is a physiological pacemaker located in the right atrium. Premature excitations originated from such as the pulmonary vein may induce arrhythmia. To establish a method to determine the origin of cardiac arrhythmia is required for radiofrequency catheter ablation treatment. The purpose of this study is to develop an system to find the origin of the premature excitation in the atria and ventricles from 12-lead electrocardiogram. Developed system can convert 12-lead electrocardiogram to vectorcardiogram, analyze vectorcardiogram for identifying the origin of premature excitation. We analyzed electrocardiograms recorded from healthy subjects and patients with premature beat. Characteristics of vectorcardiogram are clearly classified between healthy subjects and patients. Our system is useful to classify the healthy persons and patients in different groups. In this session, we will discuss the possibility of our system and methods to predict the origin of premature beat.
