WebJan 25, 2024 · Abnormalities in ECG and their Significance. Inverted P-wave indicates failure of SA node to initiate the impulse and depolarization of atrial muscles by the AV node. Enlarged P-wave is associated with enlargement of the atria. Absent Q-wave is found in infants with congenital patency of the septum, known as a ventricular septal defect (VSD). WebNov 9, 2024 · If the P is inverted with a normal PR interval (>0.12s), it’s taking a longer time to reach the ventricles than a junctional P wave would (<0.12s).
