Changes in P wave duration and morphology can provide essential information about the health of the atria, aiding in the diagnosis of various cardiac conditions. The P wave is a small positive deflection on an electrocardiogram (ECG) that represents the electrical depolarization of the atria. It occurs before the QRS complex and signifies atrial contraction. Typically, the P wave duration is less than 0.12 seconds, reflecting the normal time for atrial depolarization.

In cases of abnormal P wave duration, the ECG can indicate underlying pathology. Prolonged P wave duration may suggest atrial enlargement or other conditions affecting atrial function. On the other hand, a shorter P wave duration may indicate abnormal electrical pathways in the heart. P wave morphology, the shape and appearance of the P wave, is also important in diagnosis. Changes in P wave morphology can provide insights into left and right atrial abnormalities, such as hypertrophy and enlargement, which are associated with certain cardiac conditions.
