<p>Implantable leads incorporating accelerometer based cardiac wall motion sensors (168, 169, 468) and a method of fabricating such leads, are provided. The cardiac wall motion sensors (168, 169, 468) transduce accelerations of cardiac tissue to provide electrical signals indicative of cardiac wall motion to an implantable cardiac stimulating device. The implantable cardiac stimulating device (302) may use the electrical signals indicative of cardiac wall motion to detect and discriminate among potentially malignant cardiac arrhythmias. In response to a detected abnormal cardiac rhythm, the cardiac stimulating device (302) may deliver therapeutic electrical stimulation to selected regions of cardiac tissue.</p> |
