<p>Systems and methods for providing a cardiac stimulus device lead having fault tolerance and fault isolation are disclosed. A medical electrical lead is provided according to one aspect. According to one embodiment, the lead includes a first conductor and a second conductor for transmitting an electrical pulse from a pulse generator. The lead further includes a switching mechanism, a first electrode, and a lead assessment circuit. The switching mechanism selectively couples the first conductor to the first electrode. The first electrode is decoupled during a test phase and the switching mechanism directly couples the first conductor to the second conductor. The lead assessment circuit processes a signal associated with the electrical properties of the lead to determine whether the lead is exhibiting a lead related condition.</p>
