First seen Feb 02, 2026 · Last updated May 13, 2026 · Updated 9 times

Summary

This study tests whether a guided breathing technique called heart rate variability biofeedback (HRVB) can lower anxiety in adults waiting for a heart transplant in the ICU. Participants will use a breathing device or app during one session and complete short anxiety questionnaires before and after. The goal is to see if this simple relaxation method helps patients feel more in control of their emotions during a stressful hospital stay.
