Which statement is true about BIOTRONIK impedance monitoring?

• A. They measure shock impedances along with pacing impedances
• B. They require manual entry to check impedance
• C. They do not report trends
• D. They only report quarterly

Answer: (A)

The key idea is that BIOTRONIK impedance monitoring tracks both pacing and high‑voltage/defibrillator circuits to assess lead condition. By measuring pacing impedance, the device checks the resistance in the pacing lead circuit, which can rise if there’s lead fracture, poor contact, or insulation issues. By measuring shock impedance, it evaluates the resistance in the defibrillator circuit, which can change if the coil or conductor is damaged or insulation has degraded. Because these systems continuously monitor and often transmit data automatically, they provide trends over time rather than requiring manual entry or limited, infrequent reports. That makes the statement about measuring both shock and pacing impedances the true description of BIOTRONIK impedance monitoring.
