Hiroshi Inoue,Akira Fujiki,Hideki Origasa,Satoshi Ogawa,Ken Okumura,Isao Kubota,Yoshifusa Aizawa,Takeshi Yamashita,Hirotsugu Atarashi,Minoru Horie,Tohru Ohe,Yoshinori Doi,Akihiko Shimizu,Akiko Chishaki,Tetsunori Saikawa,Katsusuke Yano,Akira Kitabatake,Hideo Mitamura,Itsuo Kodama,Shiro Kamakura +19 more
TL;DR: The prevalence of AF increased in Japan as the population aged, as in Western countries, and the overall prevalence in Japan is approximately two-thirds of that in the USA.
Journal ArticleDOI

Tohru Ohe,Katsuro Shimomura,N Aihara,Shirou Kamakura,Mokuo Matsuhisa,Iwao Sato,H Nakagawa,Akihiko Shimizu +7 more
TL;DR: In this paper, the authors performed electrophysiologic studies in 16 patients with idiopathic sustained (lasting more than 5 min) ventricular tachycardia (VT) originating from the left ventricle.
Journal ArticleDOI

TL;DR: Three-dimensional (3D) mapping systems that have been developed since the 1990 s have contributed to the clarification of the mechanisms of these complex arrhythmias and the improvement of the outcome of ablation procedures.
Journal ArticleDOI
Target international normalized ratio values for preventing thromboembolic and hemorrhagic events in Japanese patients with non-valvular atrial fibrillation: Results of the J-RHYTHM registry
Hiroshi Inoue,Ken Okumura,Hirotsugu Atarashi,Takeshi Yamashita,Hideki Origasa,Naoko Kumagai,Masayuki Sakurai,Yuichiro Kawamura,Isao Kubota,Kazuo Matsumoto,Yoshiaki Kaneko,Satoshi Ogawa,Yoshifusa Aizawa,Masaomi Chinushi,Itsuo Kodama,Eiichi Watanabe,Yukihiro Koretsune,Yuji Okuyama,Akihiko Shimizu,Osamu Igawa,Shigenobu Bando,Masahiko Fukatani,Tetsunori Saikawa,Akiko Chishaki +23 more
TL;DR: An InR of 1.6 is safe and effective at preventing thromboembolic events in patients with NVAF, particularly patients aged ≥70 years, and an INR of 2.99 is also effective, but associated with a slightly increased risk in major hemorrhage.
