Blood pressure cuff may spot hidden heart rhythm problem
NCT ID NCT07442175
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a special blood pressure monitor can accurately detect atrial fibrillation, a common heart rhythm disorder. Researchers will compare the monitor's readings with standard diagnostic methods in 392 adults, some with and some without AF. If it works, this could make screening for AF easier during routine checkups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Blood pressure monitor (TH-75) with atrial fibrillation detection function
- What this could lead to
- If successful, this could provide a simple way to detect atrial fibrillation during routine blood pressure checks, potentially leading to earlier diagnosis.
- What could go wrong
- This is a diagnostic accuracy study, not a treatment trial. The device may not be accurate enough to replace standard ECG diagnosis, and results may not apply to people with pacemakers or other conditions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Atrial Fibrillation (AF): * Age ≥ 22 years; * Arm circumference between 22 cm and 42 cm; * Diagnosed with atrial fibrillation by a qualified medical institution. Non-Atrial Fibrillation: * Age ≥ 22 years; * Arm circumference between 22 cm and 42 cm; * No prior diagnosis of atrial fibrillation. Exclusion Criteria: * Pregnant women * Presence of an implanted cardiac pacemaker and/or defibrillator * Inability to cooperate with blood pressure measurement or ECG assessment * Any condition that, in the opinion of the investigator, makes the participant unsuitable for participation in this clinical study
