About Tawara-Aschoff Symposium

 We would like to express our gratitude and extend an invitation to participate in the 13th Tawara-Aschoff Symposium (TAS).

 TAS honors Sunao Tawara, pioneering cardiologist of Japan, who discovered the cardiac electrical conduction system of the heart in the beginning of the 20th century. The cardiologists of those days were full of unexplained things, and the controversy about heart beat was also controversial about the neuromatism and the myogenic theory (the theory of whether the heart's beating was caused by nerves or myocardium). He published an original work (Figure) of about 200 pages titled "Stimulation conduction system of mammalian heart - anatomical and histological study of atrioventricular connection bundle and Purkinje fiber" in 1906. The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The main components of the cardiac conduction system are the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers. The SA node (anatomical pacemaker) starts the sequence by causing the atrial muscles to contract. From there, the signal travels to the AV node, through the bundle of His, down the bundle branches, and through the Purkinje fibers, causing the ventricles to contract. This achievement is said to be a discovery worthy of the Nobel Prize is a cornerstone of the development of current cardiac physiology and clinical heart research, because it was a great accomplishment that establishes the electrocardiography method and the foundation of pacemaker development.

 The 1st TAS was held in Marburg 1 July 9, 1999. Since then Japan and Germany have been held almost alternately every other year, in Japan and Germany, with the aim of developing state-of-the-art medicine in the treatment of cardiac arrhythmia, many medical work engaged in day-to-day medical treatment and research. As shown in the appendix table, we have held twelve symposiums so far, and the number of participants continues to increase each time we repeat the number of times. This years’ TAS, to take place immediately after the ‘SIJM 2019’ joint scientific meeting, will feature discussions on up-to-date topics with a multinational group of participants. You are cordially invited to attend and actively participate in the discussions.

 We thank you for your support and cooperation to continue this regular symposium on a regular basis in the future.
