| The P wave is admitted to be the wave of auricular contraction. |
| In an ECG, atrial systole is associated with atrial depolarization, or the P wave deflection. |
| P wave amplitudes were unaffected with the onset of diabetes. |
| P wave indices derived from the standard ECG are P wave duration, morphology, and amplitude and provide information about the atrial electrical activity. |
| P wave inversion was observed in diabetic group which is indicative of abnormality of SA node. |
