Can moving ECG stickers to the temples give sharper heart readings during surgery?
NCT ID NCT07719777
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
During general anesthesia, doctors use an ECG to monitor the heart. For shoulder surgery, standard electrode spots are in the way, so alternatives like the breastbone are used—but these can give fuzzy readings. This trial tests two modified placements—one on the sternum and one near the temples—to see which matches the standard ECG most closely. Adults aged 19 to 65 scheduled for non-shoulder surgery under general anesthesia will participate, and researchers will compare the waveforms blindly.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could establish a reliable alternative ECG lead placement for patients undergoing shoulder surgery, improving heart monitoring during anesthesia.
- What could go wrong
- This is a small, early-stage study focused on waveform similarity rather than clinical outcomes. The modified placements may not prove superior in detecting real heart problems.
