Summary

This study tests whether a guided breathing technique called heart rate variability biofeedback (HRVB) can reduce anxiety in 60 adults who are in the ICU waiting for a heart transplant. Participants will use a biofeedback device or app during a single session led by a trained clinician. The goal is to see if this simple, non-drug approach helps patients feel calmer and more in control during a very stressful time.

What this could mean

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

Active substance: Heart Rate Variability Biofeedback (HRVB) - a guided breathing technique using a biofeedback device or app
What this could lead to: If it works, this could offer a simple, drug-free way to help heart transplant candidates manage anxiety while in the ICU.
What could go wrong: This is a very small, early-stage study with only 60 participants. The intervention is a single session, so any benefits may be short-lived. Results may not apply to all patients.
