This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are testing whether a specialized 3D heart mapping system can accurately pinpoint the exact location of the abnormal pathways causing nodal tachycardia—a condition where your heart suddenly beats very fast due to a short circuit in the heart's electrical system. The study will compare detailed mapping scans from patients with this condition to patients without it, to see how well the technology can identify these problem areas before treatment.
Currently, doctors use basic imaging to guide treatment of nodal tachycardia, but this new high-resolution mapping technology may provide much more precise location information, potentially making ablation procedures (which destroy the abnormal tissue causing the fast heartbeat) safer and more effective.

If you qualify, you will undergo a specialized 3D heart mapping procedure using the RHYTHMIA HDx mapping system and a special catheter (a thin tube inserted into your heart). The research team will create detailed maps of the area around your AV node and compare these maps to where treatment is actually performed. This is a single-center study at University Hospital in Toulouse, and the procedure is part of your standard care for your heart rhythm condition.
