WebMay 3, 2024 · It is measured from the conclusion of the T-P segment (P wave onset) to return to baseline (PR interval). For biphasic P-waves, P-wave duration encompasses both positive and negative deflections from baseline. Prolonged P-wave duration is present if the maximum P-wave duration in any lead is >120 ms on a standard 12-lead ECG (32, 33). WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size. how many innings in professional baseball
