Device evaluation of electrode belt has been completed.The reported problem (ecgs non-functional) has been confirmed.Upon investigation the electrode belt failed an ecg fall-off test.The cause for the failure was isolated to a short in ecg "c".An unused pulse wire in the cable migrated into ecg electrode, causing a short.A root cause investigation determined that the cause of the unused wire migration in the ecg ¿c&d¿ cable was the lack of a method to secure the unused wire ends.No adverse event resulted from the damaged belt.
