WebFeb 15, 2024 · The P wave on an ECG trace is indicative of atrial depolarisation, which may be initiated by the sinoatrial node or by an ectopic atrial focus. Normal P Wave Size; … WebP wave morphology provides a useful guide to the localization of focal AT. ECG lead V1 is the most useful in identifying the likely anatomical site of origin for focal AT. Lead V 1 is located to the right and anteriorly in relation to the atria, which should be considered as right anterior and left posterior.
