Polybenzimidazole fiber. Polybenzimidazole (PBI, short for poly[2,2â-(m-phenylen)-5,5â-bisbenzimidazole]) fiber is a synthetic fiber with a very high melting point. It has exceptional thermal and chemical stability and does not readily ignite.
It is important to remember that the P wave represents the sequential activation of the right and left atria, and it is common to see notched or biphasic P waves of right and left atrial activation. 1  P duration < 0.12 sec. 2  P amplitude < 2.5 mm.  Frontal plane P wave axis: 0Â° to +75Â°.
