Abstract
Embodiments of the present invention are directed to devices, systems and methods for pacing and sensing, in a chamber of a patient's heart, that provide for good sensed R wave amplitudes and capture thresholds, yet avoids extracardiac stimulation. Such benefits are achieved by using what is referred to herein as a 'distributed' anode, where one portion of the anode is within 5 mm of the cathode, but another portion of the anode is at least 10 mm from the cathode. While especially useful for pacing and sensing in the left ventricle, embodiments of the present invention can be used to pace and sense in any chamber of the heart.
