Energy Delivery

Most PFA waveforms use square waves as the basis of energy delivery. Arga is unique in using sine waves. Inherent benefits of sine waves include delivery of more therapeutic energy, lesion depth titration, and patient safety.

Sinewaves Provide Flexibility in Energy Delivery

Arrhythmias can arise in all chambers of the heart. The thickness of the heart tissue is variable, necessitating flexibility in energy delivery to create durable lesions to treat all cardiac arrhythmias.

Unipolar Energy Delivery — In phase (0◦)

Enhances lesion depth when creating focal lesions

Bipolar Energy Delivery — 180◦ phase

Fills gaps between electrodes when creating circular and linear lesions

Combination Energy Delivery — Between 0◦–180◦

Fills gaps between electrodes and enhances depth over bipolar only when creating circular and linear lesions
