New vest-like device could map heart rhythm problems without needles
NCT ID NCT05772182
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new non-invasive tool called ECG-Imaging that uses many electrodes on the body to create a 3D map of the heart's electrical activity. The goal was to see if it can more accurately locate the source of heart rhythm problems compared to a standard ECG. 362 participants who were already scheduled for an invasive heart procedure took part. The results will show whether this technology can help doctors plan treatments like ablation without needing as many invasive tests.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ACORYS MAPPING SYSTEM (ECG-Imaging device)
- What this could lead to
- If successful, this could give doctors a more accurate, non-invasive way to pinpoint the source of heart arrhythmias, potentially improving treatment planning.
- What could go wrong
- This is a completed diagnostic accuracy study, not a treatment trial. The new mapping system may not prove more accurate than standard methods in all cases.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Indication for an invasive electroanatomic study and/or intracardiac device implantation. * Having obtained and signed the informed consent for study participation. * Ability to stand, to be able to obtain the 3D torso reconstruction necessary for the ECGI system. Exclusion Criteria: * \<18 years old * Inability to perform an endocardial catheterization and/or device implantation. * Physical or mental disability to understand and accept the informed consent. * Inability to stand to obtain the 3D torso reconstruction. * active coronary ischemia or decompensated heart failure * Intracardiac clot on trans-esophageal echocardiography * Pregnancy. * Disorganized arrhythmias (i.e. atrial fibrillation, polymorphic ventricular tachycardia).
