Autor: Tadasi Tamai, Takasi Yanaga, Masayosi Goto

Publikováno v: The Japanese Journal of Physiology. 11:656-665

1. Fibrillation was induced through the administration of aconitine on the right atrium isolated from a young rabbit, and the electrical activity was recorded simultaneously from two fibers of the fibrillating atrial muscle.2. Synchronism in activiti

Publikováno v: Japanese Heart Journal. 5:380-388

A case of ventricular paroxysmal tachycardia with abnormal P waves is presented. As regard to the identification of P waves during paroxysm, the high gain electrocardiogram is more useful than the conventional electrocardiogram. The P wave abnormalit

Studies on Aconitine-induced Arrhythmias

Autor: Kazuyuki Saeki, Morio Ito, Takasi Yanaga, Hiroto Mashiba, Makoto Arita, Mitsuo Tanoue

Publikováno v: Japanese Heart Journal. 7:505-511

The ectopic pacemaker formation by aconitine in the left superior vena cava proximal to the heart was studied in rabbit.(1) Aconitine produced the automatic activities in the isolated strip of vena caval muscle.(2) During the recovery from aconitine

STUDIES ON THE APPEARANCE AND TERMINATION OF ACONITINE-INDUCED ATRIAL FIBRILLATION WITH MICROELECTRODES

Autor: Takasi Yanaga, Masayosi Goto, Tadasi Tamai

Publikováno v: The Japanese Journal of Physiology. 13:196-207

1. Aconitine-induced fibrillation was studied on the right atrium isolated from a young rabbit, and the electrical activity from two fibers was traced simultaneously in order to clarify the mechanism of the appearance and termination of the fibrillat

Studies on transmembrane action potentials and mechanical responses of the venae cavae and atria of the rabbit

Autor: Kazuyuki Saeki, Hiroto Mashiba, Morio Ito, Mitsuo Tanoue, Takasi Yanaga, Makoto Arita

Publikováno v: The Japanese journal of physiology. 16(4)

1. In the rabbit, there exist three venae cavae which empty into the right atrium (RA) by separate ostia: the left superior vena cave (LSVC), the right superior vena cava (RSVC), and the inferior vena cava (IVC). Electrical and mechanical responses o
