What this study is about
The objective of the RHAPSODY study is to evaluate the performance of new software features in subjects undergoing the usual treatment catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System.
View original scientific description
The objective of the RHAPSODY study is to evaluate the performance of new software features in subjects undergoing standard of care catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System. Results from this study will be used to guide development and refinement of new software features that may be implemented in future commercial software releases.
Interventions
DEVICE
Rhythmia Mapping System
The Rhythmia Mapping System is a 3D electro-anatomical mapping system.
Primary outcome measures

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age 18 or above, or above legal age and willing and capable of giving informed consent specific to national law
- Scheduled for standard of care catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System.
Exclusion criteria
- Prothrombotic or bleeding tendency due to coagulopathy or blood dyscrasia
- Inability to tolerate heparin therapy (e.g. heparin induced thrombocytopenia, allergy, etc.)
- Prosthetic or stenotic valves in the chamber where the intended mapping will occur, or in the path of the catheter access route
- Active systemic infection or sepsis
- Hemodynamic instability or shock at baseline precluding ablation in the assessment of the investigator.
- Presence of intracardiac thrombus, tumor, or other abnormality which precludes catheter introduction
- Women who are pregnant or lactating
- Cardiac surgery within the past 90 days
- Acute myocardial infarction within 3 months
- Stable/unstable angina or ongoing myocardial ischemia
- Subjects with an active heart failure decompensation
- Long QT Syndrome, Brugada Syndrome, or Torsade de Pointes
- Congenital heart disease with or without corrective surgery that would complicate a mapping procedure
- Subjects having untreatable allergy to contrast media
- Vascular pathology or tortuosity precluding standard vascular access techniques
- Subjects who are currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the patient is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments. Each instance should be brought to the attention of the sponsor to determine eligibility.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
