In impedance monitoring, which reading would most likely indicate a healthy lead contact?

Impedance readings reflect how well the lead tip is in contact with tissue and how intact the lead assembly is. A healthy lead contact typically shows a moderate impedance in the normal range, roughly 300–1200 ohms, indicating good tissue contact and a normal current path. Zero ohms would mean a direct short, which is abnormal and suggests a problem with the lead or connection. Impedance in the megaohm range points to an open circuit or very poor contact, also indicating an issue with the lead or insulation. Lastly, impedance values are indeed related to lead health; ignoring impedance would miss clues about contact quality or lead integrity. So, an impedance reading within the typical range is the best indicator of healthy lead contact.
