Summary

This study checks how well a new algorithm can detect irregular heartbeats using sensors on the finger and wrist. It involves 120 healthy adults aged 18 to 80. The goal is to see if the device works accurately compared to a standard heart monitor.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Subject is 18 to 80 years of age. * Comfortable to read and communicate in English.\* * Subject passes the health assessment conducted by qualified study personnel, confirming they are in adequate health to participate in the required procedures * This is to ensure the participant can provide informed consent and can comply with study procedures (as study material are currently available in English only). Exclusion Criteria: * Subject currently has a known cardiac disease condition. * Subject is pregnant or breastfeeding. * Subjects with a skin condition affecting the digits/chest, where the sensors are applied which would interfere with the path of lights (e.g., psoriasis, vitiligo, eczema, angioma, scar tissue, burn, fungal infection, substantial skin breakdown) or sensor adhesion. * Skin condition which would preclude proper ECG placement. * Subjects with nail polish or acrylic nails on the digits where sensor needs to be applied, who opt not to remove them. * Subject is allergic to any supplies used in the study (e.g., ECG gel, adhesives). * Subject has any medical condition which in the judgment of the investigator and/or study staff, renders them ineligible for participation in this study or subject is deemed ineligible by the discretion of the investigator/study staff.
