Clinical Validation of the Norbert Health Device for Pulse Rate Measurement

The study design is to validate the pulse rate accuracy. The study is a non-randomized, non-blinded single arm design to evaluate the clinical accuracy of the ND's pulse rate measurement compared to a reference heart rate manually measured by observing R-peaks in a standard concurrently recorded ECG from an FDA 510(k)-cleared reference clinical ECG (RCECG). The sponsor will ensure that the study staff enrolls a range of subjects.
