It is my great pleasure and honor to invite you to the 10th Asia Pacific Heart Rhythm Society Scientific Session (APHRS 2017), which will be held September 14–17, 2017, in Yokohama, Japan. This is a milestone session since the first APHRS 2008 in Singapore, and I would like to congratulate all members, contributors, and guests on the successful growth of the APHRS.

In the last 10 years, there has been impressive evolution and innovation in the fields of cardiac electrophysiology, electrocardiology, and arrhythmia management. For example, proper management of atrial fibrillation has been a challenge, and recent technologies for ablation such as 3-dimensional mapping systems, contact force sensing catheters and high-resolution mapping, as well as the development and launch of direct oral anticoagulants, have substantially altered and improved its management. With these robust developments, the science of cardiac arrhythmias in the APHRS countries has greatly improved, and many novel findings and information have been generated by APHRS members and published worldwide. As a result, the APHRS scientific session is highly evaluated and will continue to develop in the future.

The 10th APHRS will be held in conjunction with the Annual Meeting of the Japanese Heart Rhythm Society2017(JHRS) (Congress President: Kenzo Hirao, Tokyo Medical and Dental University). As stated by Prof. Hirao, the scientific session will cover all of the recent advances in cardiac arrhythmias, electrophysiology and electrocardiology. I am sure that by attending the joint scientific sessions of APHRS and JHRS 2017, all participants will be impressed and satisfied with the level of science in the APHRS region. I and the scientific session committee members look forward to welcoming you to Yokohama facing the beautiful Tokyo Bay area in September 2017 under the title “Advancing Together in Heart Rhythm”.
