"SpletThe f wave is modified by the near field potential and the far field potential. The amplitude of f wave arises along with the deepening of the catheter tip. When the tip of PICC comes to the ideal position (the lower 1/3 of SVC), f wave amplitude is the highest, which is similar to the change of P wave in the normal surface ECG patients.
