Which outcome occurs when a pacemaker's lead capacitance degrades?

💡 Explanation

Increased pacing threshold results because degraded capacitance leads to reduced charge storage, and less charge available reduces stimulation strength, therefore a higher voltage is required to trigger depolarization, rather than alternative changes to refractory period or acceleration.
