Abstract：Objective: To assess the value of the pseudo deta wave (PdW) in the diagnosis of different positions of premature ventricular contractions (PVCs). Methods: The radiofrequency ablation were performed.Then the length of the PdW in different positions of PVCs in totally 97 patients with PVCs was measured. Results: ①The originating of PVCs: In 13 cases it was originating from the endocardium of the left ventricle. In 52 cases it was originating from the endocardium of the right ventricle. In 27 cases it was originating from the aortic sinus. In 5 cases it was from the great cardiac vein. ②The length of the PdW in the 4 groups was different (P<0.05). The length of the PdW from the sinus of valsalva and great cardia vein was different (P<0.05).The length of the PdW from the endocardium and epicardium according to the position of the originating site was different (P<0.05). Conclusion: The length of the PdW can be used in indentifying PVCs not only arising from the endocardium and epicardium, but also arising from the sinus of valsalva and great cardia vein.
