Summary

This study uses a special catheter to record detailed electrical signals from the heart during a standard procedure for dangerous heart rhythms (ventricular tachycardia). Researchers aim to better understand why these rhythms start and how to pinpoint the exact trouble spots. Ten adults with ischemic cardiomyopathy and an implantable defibrillator will participate. The goal is to improve future ablation treatments, not to test a new therapy.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Monophasic Action Potential (MAP) Catheter (EasyMap catheter)
What this could lead to: If successful, this research could improve how doctors identify and target the exact heart areas causing dangerous rhythms during ablation procedures.
What could go wrong: This is a very small, early observational study (10 participants) focused on understanding mechanisms, not testing a treatment. Results may not lead to immediate clinical changes.
