Message from the Division Head

Treatment of arrhythmia has advanced remarkably in the past 20 years. Empiric treatment with drugs used to be the only choice, but technological innovation has given rise to catheter ablation, implantable cardioverter-defibrillator (ICD) placement, and other methods. Currently, arrhythmia can be cured in most cases. As part of these advances, our team has accomplished top-level performance in Japan and the world in the treatment of arrhythmia in terms of both quantity and quality.

We treat all types of arrhythmias, ranging from common ones such as atrial fibrillation to bradyarrhythmias requiring pacemakers or severe arrhythmias that lead to sudden death. We also diagnose and treat conditions that cause palpitations, skipped beats, dizziness, and syncope. Furthermore, we treat heart failure with resynchronization therapy (biventricular pacing). We diagnose hereditary arrhythmias with genetic testing and treat them. We are ready for all types of cardiovascular diseases.

Our division is equipped with almost all the devices needed for the diagnosis of arrhythmia, including a three-dimensional navigation system and magnetocardiography device. We implant pacemakers, ICDs, cardiac resynchronization therapy defibrillators (CRT-Ds), and other devices, and perform catheter ablation in approximately 800 patients per year. Although these diagnostic and therapeutic procedures are and will continue to be performed only in patients who need them under the strict criteria for their application, we are going to expand their application to more patients and actively introduce regenerative medicine and latest diagnostic and therapeutic devices. We are also active in research and at academic meetings related to arrhythmia. Most of us have experience as chairpersons or symposiasts at academic meetings throughout Japan.

We are not just pursuing the latest treatment. We always commit ourselves to provide compassionate and reliable medical care. We are constantly observing the clinical course of more than 4,000 patients. If you have problems in daily management of arrhythmias, or you would like to consult with us, please feel free to contact us. Our staff will respond with attention to detail and support you so that you will receive treatment with peace of mind and have a fulfilling life.
