Electrode catheter ablation is one of the remedies for atrial fibrillation (AF) which is a kind of heart disease. Catheter ablation is an operation which suppresses AF by the insertion of a catheter into the heart and burning the parts causing premature atrial contractions (PAC). However, generally, the operation takes several hours since the parts causing PAC remain to identified and reoperations are frequently required. If only the parts causing PAC can be detected, early and accurate operation would be possible. This paper describes discovering the parts causing the PAC from catheter electrocardiograms (C-ECGs) by using a novel analytical method to detect the signal derived from the heart. Patients were done the catheter ablation, and the catheter electrocardiogram was measured. In this paper we show the first, the parts causing the PAC from C-ECGs by translation error using Wayland test and Double-Wayland test. Second, it is shown that the rule of the measurement signal can be distinguished from translation error, and finally, these methods can be applied to the detection of the parts causing PAC from patient's C-ECGs.
