摘要：
In some examples, a medical device system includes an electrode. The medical device system may include impedance measurement circuitry coupled to the electrode, the impedance measurement circuitry may be configured to generate an impedance signal indicating impedance proximate to the electrode. The medical device system may include processing circuitry that may be configured to identify a first frequency component and a second frequency component of the impedance signal, and provide an indication of a location of the electrode in a patient based on the first frequency component and the second frequency component.
