Can slow breathing heal a broken heart? new study tests Device-Guided breathing
NCT ID NCT03324529
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a device that guides slow breathing can improve heart rate variability and quality of life in people who have had takotsubo syndrome (also known as broken heart syndrome). Ten patients with a history of takotsubo and ten healthy volunteers will use the RESPeRATE device at home for 15 weeks. Researchers will measure heart function remotely to see if the breathing exercises help.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- RESPeRATE device-guided slow breathing
- What this could lead to
- If it works, this could point toward a simple, drug-free way to improve heart health and well-being after takotsubo syndrome.
- What could go wrong
- This is a very small, early study with only 24 participants, so results may not apply to everyone. It is not designed to prove the device treats or prevents the condition.
