Clinical Trial Summary

Up to 185 adult test subjects to evaluate blood pressure measurement accuracy and stability of the Polso™ Watch compared to a reference blood pressure measurement.

Description:

The purpose of this validation study is to assess, in an adult population, the three fundamental clinical tests:

1. Blood pressure measurement accuracy ("accuracy test")

2. Measurement accuracy after blood pressure change ("change test")

3. Blood pressure measurement accuracy throughout the specified stability-period ("stability test") To provide evidence that the device can track changes in blood pressure, this study includes study conditions that specifically induce changes in blood pressure.

• Subject is evaluated by the investigator or clinician and found to be medically unsuitable for participation in this study.

• Patients with known sustained or non-sustained ventricular/atrial arrhythmia (Ventricular tachycardia, supraventricular tachycardia, atrial fibrillation, bigeminy, and trigeminy), and left bundle branch block.

• Patients with implantable defibrillators, pacemakers, neurostimulators, or other implantable or worn devices which may interfere with the Polso™ Watch or be affected by the Polso™ Watch in normal operation and use.

Primary	Primary Objectives: Main objective of the study is to evaluate blood pressure measurement accuracy and stability of the Polso™ Watch compared to a reference blood pressure measurement over time frame of 1 month average.	Blood pressure measurements (units: mmHg) using the Polso™ Watch device will be taken and compared to reference blood pressure measurements taken at the same time using dual auscultatory blood pressure measurements, to show their accuracy and stability.	Through study completion, 1 month average
