Abstract
An implantable medical device (IMD) may include a lead circuit including a first node configured to be coupled to a first lead that may be coupled to a first target tissue and including a second node configured to be coupled to a second lead that may be coupled to a second target tissue. The IMD may include an impedance unit that may determine at least one characteristic of coupled energy associated with the lead circuit, where the coupled energy may be produced by a source external to the IMD. The impedance unit may provide an impedance between the first node and the second node, where the impedance is selected based at least in part on a characteristic of the coupled energy. The impedance is selected to reduce the coupled energy or a negative effect associated with functionality of the IMD induced by the coupled energy.
