摘要
Techniques are provided for use with a pacemaker or other implantable medical device capable of sensing electrical signals along a set of programmable sensing vectors. In one example, electrical cardiac signals are sensed within a patient using a primary sensing vector connected to a primary sensing channel for use in controlling the delivery of therapy. If the device detects a significant drop in key signal parameters such as peak signal amplitude or slew rate, an assessment is made whether an alternate sensing vector provides improved cardiac signal sensing. During the assessment, the device can continue to sense signals along the primary channel for the purposes of controlling therapy while alternate vectors are assessed in the background. If it is determined that an alternate sensing vector provides improved cardiac signal sensing, the primary sensing channel can be switched to the alternate sensing vector for use in controlling further therapy.
