In case your smart wearable fails to detect a heart-rate signal, follow these steps to troubleshoot the issue:
TeltoHeart prioritizes measuring heart rate at rest due to challenges with accuracy during movement. This approach helps overcome potential inaccuracies caused by motion artifacts and changes in blood flow. By focusing on obtaining baseline measurements during periods of rest, TeltoHeart aims to provide more reliable data for healthcare assessments, minimizing the impact of movement on accuracy.

Nr4.png Make sure that there has been no movement.

Failure to detect wrist

TeltoHeart detects the wrist using light-based sensors (photoplethysmography), which measure blood volume changes beneath the skin by emitting and detecting light. Additionally, electrode leads in direct contact with the skin detect electrical signals generated by the heart, confirming the presence of the wrist. To ensure proper wrist detection:

Nr1.png Ensure Secure Fit:
Properly secure TeltoHeart around the lower arm, just above the wrist bone, as illustrated in the user manual. A snug fit enhances the efficiency of both sensor types.
Nr2.png Check for Hairiness:
Excessive hair on the wrist may hinder the performance of optical sensors. Ensure the skin beneath the device is free from obstructions for accurate readings.
Nr3.png Assess Skin Contact:
Anything obstructing direct skin contact, such as clothing or accessories, can impact sensor functionality. Confirm unobstructed contact for optimal wrist detection.
Nr4.png Verify Device Positioning:
Wear the device approximately 1 cm above your wrist bone. Incorrect positioning may disrupt the alignment of sensors with the skin, affecting the accuracy of detection.
