Prospective Study to Validate the Clinical Accuracy of the Norbert Device to Measure Pulse Rate

The study design is to validate the pulse and heart rate accuracy as required per ISO 80601-2-61, Clause 201.12.1.104. 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 types of arrhythmias including tachycardia, bradycardia, atrial fibrillation, bigeminy, trigeminy, and others.
