将毛细管超微电极插入心室颤动犬的心室肌纤维中，并将获得的动作电位与单极直接导联、相邻双极直接导联或同时采集的其他心电图的偏转进行比较。在心室颤动的大多数阶段，他无法在它们之间发现同步性或任何其他规则的时间关系。在心室表面不同区域的不同距离的两个点插入的微电极也未能显示任何规则的时间关系。因此支持了心室肌纤维的完全不协调。
Capillary ultramicroelectrodes were inserted into ventricular muscle fibers of dogs in ventricular fibrillation and action potentials obtained were compared with deflections of unipolar direct lead, adjoining bipolar direct lead or other electrocardiograms taken simultaneously. In most stages of ventricular fibrillation neither synehronism nor any other regular time relationship could he found between them. Microelectrodes inserted at two points variously distant on various regions of the ventricular surface also failed to show any regular time relationship. Total incoordination of ventricular muscle fibers was thus supported.
