6) since bone is less conductive than the surrounding tissue, it may increase current densities in narrow regions of tissue between the bone and the skin, resulting in lower nerve stimulation thresholds than expected.
For patients, this safety feature ensures that pacing support will be consistent despite rises in stimulation threshold (the minimum amount of energy required to elicit a heartbeat) due to drug therapy, metabolic changes, illness, or lead maturation or microdislodgment.
The low stimulation thresholds for Tendril(R) DX leads promote pacing system longevity, a clear patient benefit," states Charles Love, M.
