WebThese patterns are called "no P wave" because there are no visible P waves on the electrocardiogram (ECG). The atria are therefore inactive; they do not contribute … 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; Duration 120ms (3mm) Amplitude 2.5mm; The P wave is directed inferiorly and therefore should be positive in leads I and II. It is often biphasic in lead V1.
