What type of current is used for pacing in conduction system pacing?

• A. Direct current
• B. Alternating current
• C. Unipolar current
• D. Biphasic or monophasic electrical current

Answer: (D)

The correct answer is that pacing in conduction system pacing utilizes biphasic or monophasic electrical current. This type of current is used because it effectively stimulates the cardiac tissue, ensuring reliable capture of the myocardium during pacing. Biphasic current refers to a waveform that has two phases: one where the current flows in one direction and then reverses to flow in the opposite direction, which can reduce the risk of damage to cardiac cells and improve efficiency of pacing. Monophasic current, on the other hand, flows in a single direction and is simpler in terms of waveform but may not be as effective for all pacing scenarios. In the context of conduction system pacing, the goal is to initiate depolarization effectively to restore normal rhythm, and both biphasic and monophasic currents are designed to achieve this with optimal effectiveness and safety. The use of these currents enhances pacing performance by ensuring that sufficient energy is delivered to stimulate the conduction pathways or the myocardial tissue directly, leading to reliable and effective pacing outcomes.
