New heart scanner aims to spot hidden timing issues
NCT ID NCT06641362
First seen Sep 30, 2025 · Last updated Jun 23, 2026 · Updated 32 times
Summary
This study tests a new ultra-high frequency ECG (UHF-ECG) to see if it can better diagnose ventricular electrical dyssynchrony — a condition where the heart's lower chambers don't beat in sync. Researchers will compare it to a standard 12-lead ECG in 360 adults with bradycardia or heart failure who are scheduled for a pacemaker. The goal is to see if the new device is safer and more accurate at detecting these timing problems.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ultra-High Frequency Electrocardiogram (UHF-ECG) device
What this could lead to
If successful, this could give doctors a more accurate way to detect heart timing problems, potentially improving pacemaker therapy decisions.
What could go wrong
This is a mid-stage device study with 360 participants. The new ECG may not prove significantly better than the standard test, and results may not apply to all heart patients.
Conditions
The condition(s) this trial relates to.
As listed by the trial registrant
