What type of current does Pulsed Field Ablation (PFA) utilize?

• A. Alternating current
• B. Direct current
• C. Static charge
• D. Uniphasic current

Answer: (B)

Pulsed Field Ablation (PFA) utilizes direct current to create electric fields that induce irreversible electroporation in targeted tissue. This technique delivers short bursts of high-voltage electrical energy to cells, which lead to the formation of pores in the cell membranes. These pores disrupt normal cellular function and ultimately result in cell death, which is particularly useful in treating conditions like atrial fibrillation. Understanding the type of current used is crucial, as it defines the mechanism of action of PFA. Direct current allows for a consistent and controlled delivery of energy in pulsed fields, enabling the precise targeting of specific tissue while minimizing damage to surrounding structures.
