The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
P pulmonale), but have a low predictive value (~20%). A P wave with increased amplitude can indicate hypokalemia. It can also indicate right atrial enlargement. A P wave with decreased amplitude can indicate hyperkalemia. Bifid P waves (known as P mitrale) indicate left-atrial abnormality-e.g. dilatation or hypertrophy.
