Association of P‐Wave Duration Dispersion and Terminal Force in Relation to P‐Wave Axis among Outpatients

摘要

While P‐wave duration (P‐dur) and dispersion (P‐disp) could both reflect fractionated and inhomogeneous propagation of sinus cardiac impulses, and may therefore be associated with each other, a clear relationship has not been extensively studied. We studied these markers as well as the significance of P‐wave terminal force in lead V1 (PTFV1) in relation to the P‐wave axis (P‐axis).
