An impedance measurement of 700 ohms is most consistent with which assessment?

Impedance testing looks at how easily current can flow from the lead into the surrounding tissue. A healthy lead contact produces a mid-range impedance that reflects a good conductive path with no breaks. An impedance around 700 ohms sits in the normal range for a functioning lead, indicating the tip is well seated and the conductor integrity is maintained. If there were a short circuit, the impedance would drop much lower because current would find an easier path, often yielding a very low reading. If there were an open circuit, the impedance would spike to a very high value or infinity due to a break in the conductor. An indeterminate condition means the reading is unreliable or unclear, not a stable normal value.
