title: [Characteristics of body surface mapping in the cases of idiopathic ventricular fibrillation].
abstract: Body surface mapping was recorded in three patients with idiopathic ventricular fibrillation (VF). A late r' wave appeared and disappeared in the precordial leads in all three patients. In one case, the late r' wave appeared with epithides of VF. In the presence of the late r' wave, the QRS duration was extremely prolonged. However, the appearance time of the breakthrough in the QRS isopotential map was not significantly prolonged. The time of the peaks of the r' wave was elongated in the mid anterior chest. These findings suggest that peripheral conduction disturbances in the right ventricle are related to the occurrence of VF in patients with idiopathic VF.
