TH-75 blood pressure monitor for detecting atrial fibrillation

Blood Pressure Monitor (TH-75) Atrial Fibrillation Detection Function Clinical Trial

Observational Andon Health Co., Ltd · NCT07442175

What this trial studies

This observational study compares readings from the TH-75 blood pressure monitor with a standard diagnostic method (ECG) to measure the device's accuracy for atrial fibrillation detection. Adults aged 22 and older with an arm circumference of 22-42 cm, both people diagnosed with AF and those without known AF, will have simultaneous device and ECG measurements. Participants who are pregnant, have an implanted pacemaker or defibrillator, or cannot cooperate with measurements will be excluded. The trial is conducted at the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine in Tianjin, China.

Who should consider this trial

Good fit: Ideal candidates are adults aged 22 or older with arm circumference 22-42 cm who can cooperate with blood pressure and ECG measurements, whether they have a prior AF diagnosis or not.

Not a fit: Patients with implanted pacemakers or defibrillators, pregnant people, those with arm circumference outside 22-42 cm, or those unable to cooperate with measurements are unlikely to benefit.

Why it matters

Potential benefit: If accurate, the TH-75 could enable easier routine blood pressure checks to spot atrial fibrillation sooner and prompt timely care.

How similar studies have performed: Previous studies of blood-pressure devices with AF-detection algorithms have shown promising but variable accuracy, so device-specific testing is needed.
