Using deep learning to detect pulmonary hypertension with a digital stethoscope and ECG.
Official title: Deep learning for algorithmic detection of pulmonary hypertension using a combined digital stethoscope and single-lead electrocardiogram
Funded at Eko Devices, INC. · NIH-10930932 · Data updated 2026-11-12
This study is working on a smart computer program that uses sounds from a digital stethoscope and heart readings to help find pulmonary hypertension early, making it easier for patients to get the care they need without uncomfortable tests.

Who could benefit from this research
✓Could help
Ideal candidates for this research are adults who may be at risk for pulmonary hypertension and require screening.
✕Less likely to help
Patients who are under 21 years old or those who have already been diagnosed with pulmonary hypertension may not benefit from this research.
What this research studies
This research aims to develop a deep learning algorithm that can screen and detect pulmonary hypertension (PH) using data from a digital stethoscope and electrocardiogram (ECG). The Eko DUO device records phonocardiogram and ECG data, which is then analyzed by the algorithm to identify patients who may have PH. By creating a database of matched recordings and testing the algorithm, the goal is to improve early diagnosis and treatment of this condition, which is often missed due to the invasive nature of traditional diagnostic methods.
Why it matters
Potential benefit: If successful, this research could lead to earlier and more accurate diagnoses of pulmonary hypertension, improving treatment outcomes for patients.
How similar studies have gone: Other research has shown promise in using digital tools and algorithms for early detection of various conditions, suggesting potential success for this approach.
