The anode (+) part of a pacemaker lead is defined as:

Explanation:
In pacing circuits, current flows from the anode to the cathode to complete the loop. The pacing impulse is delivered at the cathode into the heart, causing depolarization of the myocardium. The return path for that current goes to the anode, which is why the anode is described as receiving the impulse after the depolarization has occurred. The anode is typically not embedded directly in heart tissue (that’s more the role of the cathode tip), and sensing or mechanical anchoring are separate functions.
