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

Study Overview
=================
Brief Summary
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Patient-reported PSVT.<br>Participants who recorded a PSVT diagnosis. | |
| Suspected PSVT.<br>Participants who do not record a PSVT diagnosis. | |
| Other subgroups.<br>Subgroups also may be examined ( PSVT-episode characteristics, use of a self-management technique for PSVT at home (on their own) to return heart rate back to normal).The sample size, however, may limit the extent of any subgroup analyses. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient Reported Frequency of Recurring PSVT Episodes Using a Patient-Directed Survey Developed by Milestone Pharmaceuticals. | The patient is able to report the frequency (number of PSVT episodes per day, week, month, etc.) for each of their recurring PSVT episodes. Changes in PSVT episode frequency over time will also be assessed. | Baseline, then every three months for up to 10 years | 
| Patient Reported Duration of Recurring PSVT Episodes Using a Patient-Directed Survey Developed by Milestone Pharmaceuticals. | The patient is able to report the duration (seconds, minutes, hours, etc.) for each of their recurring PSVT episodes. Changes in PSVT episode duration over time will also be assessed. | Baseline, then every three months for up to 10 years. | 
| Patient Reported Severity of Recurring PSVT Episodes Using a Patient-Directed Survey Developed by Milestone Pharmaceuticals. | The patient is able to report the severity (1, not severe at all - 5, extremely severe) for each of their recurring PSVT episodes. Changes in PSVT episode severity over time will also be assessed. | Baseline, then every three months for up to 10 years. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient Reported Descriptions of the Symptoms to Characterize Their Recurring PSVT Episodes Using a Patient-Directed Survey Developed by Milestone Pharmaceuticals. | The patient is able to report the most common symptoms that they use to describe each of their recurring PSVT episodes. Changes in PSVT episode symptoms over time will also be assessed. | Baseline, then every three months for up to 10 years. | 
| Patient Reported Descriptions of Health Resource Utilization to Manage Their Recurring PSVT Episodes Using a Patient-Directed Survey Developed by Milestone Pharmaceuticals. | The patient is able to report physician visits, emergency room visits, hospital admissions, surgical interventions, medication use, monitoring device use, and patient self-management techniques, which are used to assess health resource utilization for each of their recurring PSVT episodes. | Baseline, then every three months for up to 10 years. |
