The mechanism of cardiac fibrillation and flutter should be investigated not only from the viewpoint of the abnormality of the electrical activity of the cardiac cells but also from that of the cardiac tissue. As a matter of fact, the mechanism was p

In the isolated rabbit hearts the presence of an electrical longitudinal dissociation in the atrial portion of the His bundle was examined by the microelectrode method. Under the normal condition no marked differ-ence was found in the duration of the

Action potentials of premature beats in ventricular muscle fibers showed a transient prolongation of duration as well as an increase in second depolarization of the plateau phase when the preceding diastolic intervals were progressively shortened. Th

Summary Employing a summation method with a computer, the U vector loop can be obtained in a reproducible and reliable way. In this study we found that the U main vector loop in normal subjects was directed anteriorly, inferiorly and mostly slightly

By employing electrographic electrodes, suction electrodes and microelectrodes, 2 conduction pathways were discovered in the anteromedial portion and in the posteromedial portion along the AV ring at the lower margin of the left atrium in the isolate

A comparison was made of the electrophysiological properties of the fibers between the previously reported conduction pathways from the left atrium to the right atrium and to the ventricle (left A-V ring pathways) and the ordinary atrial muscle, usin
