The PSVT Place Registry.Paroxysmal Supraventricular Tachycardia (PSVT) Registry.

Paroxysmal supraventricular tachycardia (PSVT) is a sporadic, sudden, and recurring
tachycardia that is caused by an altered electrical conductivity in the heart. It causes
palpitations and a rapid heart rate, which may induce fear in the patient and negatively
impact the patient's quality of life. Therefore, most patients experience not only physical
symptoms of PSVT, but also dramatic psychological burdens.

As PSVT drug development efforts advance, it has become increasingly important to document
the impact of PSVT in a systematic way, in terms of the disease natural history and clinical
characteristics of PSVT episodes, as well as the psychological impact of the condition as
reported by patients over time. In order to meet the needs for ongoing, systematic data
collection on PSVT, a multinational registry, The PSVT Place Registry
(www.PSVTPlaceRegistry.com), is being implemented and will be initially comprised of data
entered directly by patients. The long-term registry is designed with a participant-focused
approach to enable continuity of data collection and minimization of impact from changes of
participants' health care providers. The registry may be expanded at a later time to include
physician-reported data.

The information from the registry is planned to be a resource for participants with PSVT,
their families and support networks, their doctors, and the research community to better
understand PSVT-related symptoms and awareness, PSVT diagnoses, patient self-management,
medical treatments for PSVT, and impact of PSVT on quality of life from the patient
perspective.
