Webb21 sep. 2024 · The P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization. What is normal P wave in ECG? The P-wave is frequently biphasic in V1 (occasionally in V2). The negative deflection is normally <1 mm. P-wave duration should be ≤0,12 seconds. Webb29 jan. 2024 · The electrocardiogram (ECG) is a valuable diagnostic test in veterinary medicine and is easy to acquire. It is the most important test to perform in animals with an auscultable arrhythmia (other than sinus arrhythmia in dogs).
