Hi, thanks for your interest in Biostrap!
I double-checked with my team, and they sent me the following information:
Most household equipment in good condition poses little if any risk to your ICD when they are used properly. However, it is best to keep them at least 6 inches (15 cm) away from your ICD site. Primarily keep the motors and antennae 6 inches from your ICD.
They also let me know that we are currently designing a clinical study with Cleveland Clinic to give wristbands to patients with ICDs.
I hope this helps! :)
Please let me know if there are any other questions I can assist with.
