摘要：
A system includes a memory and a processing module. The memory includes a primary sensing vector and N alternate sensing vectors. The processing module determines a ranking value for each of the N alternate sensing vectors. Each ranking value is indicative of the integrity of a cardiac electrical signal acquired via the corresponding alternate sensing vector. The processing module senses cardiac events using the primary sensing vector, detects a reduction in the integrity of a cardiac electrical signal acquired via the primary sensing vector, and selects one of the N alternate sensing vectors in response to detecting a reduction in the integrity of the cardiac electrical signal acquired via the primary sensing vector. The selection is based on the ranking value associated with the one of the N alternate sensing vectors. The processing module then senses cardiac events using the selected one of the N alternate sensing vectors.
