WebP-wave duration should be <0,12 s (all leads). P-wave amplitude should be ≤2,5 mm (all leads). PR interval must be 0,12–0,22 s (all leads). Common findings P-wave must be positive in lead II, otherwise the rhythm cannot be sinus rhythm. P-wave may be biphasic (diphasic) in V1 (the negative deflection should be <1 mm). WebFor instance note in the EKG segment below that there is a P-wave before each QRS (highlighted in blue) and that it is pointing up as is the QRS segment.
