WebP wave indicate the depolarisation of Atrium. QRS indicates the depolarisation of ventricle. T wave indicates the Repolarisation of Ventricle. View the full answer Final answer Previous question Next question This problem has been solved! WebThe P wave represents atrial contraction. P waves are normally evenly rounded and either positive or negative in all leads except V1, where a biphasic wave is sometimes seen. Its duration should be less than 0.12 seconds and its amplitude less than 0.25 mV. Right atrial hypertrophy (e.g., due to pulmonary hypertension) results in peaked P waves.
