An abnormal ECG P-wave is an abnormal change in the potential of atrial depolarization, which is most commonly seen in pulmonary heart disease, atrial hypertrophy, potassium abnormalities, and cardiac arrhythmias.
P-wave refers to the normal process of atrial depolarization, the electrocardiographic vector from the sinoatrial node to the atrioventricular node, and the depolarization from the right atrium to the left atrium, which will be abnormal under the influence of various factors.
Increased peak P wave suggests right atrial hypertrophy, pulmonary heart disease and other diseases. A bimodal P wave suggests left atrial enlargement or hypertrophy.
An increase in P-wave amplitude suggests hypokalemia or enlargement of the right atrium, while a decrease in amplitude may suggest hyperkalemia.
In case of atrial flutter or atrial fibrillation, i.e. arrhythmia, the shape, direction and frequency of P wave will change or even disappear.
If P-wave abnormality is found in ECG, patients should seek medical treatment in time and under doctor’s guidance, and should not take medication without authorization. Reasonable arrangement of working time and pay attention to rest.
