Pathologic signs of left atrial load are found very often in arterial hypertension. The diagnostic combinations are very slightly expressed, more often in the orthogonal ECG. Pathologic criteria found most often are: pathologic end-strength of the P wave in lead V1 (in 42% of the patients) and increased amplitude of PX (in 39% of the patients). The pathologic changes of the P wave increase with the development of left ventricular hypertrophy and heart failure. The values of the end-strength of the P wave in lead V1 when they are negative more than - 0.03 mm.s should be considered pathologic in contrast to mitral valvular disease.
左心房负荷的病理征象在动脉高血压中很常见。诊断组合表现非常轻微，更多见于正交心电图。最常发现的病理标准是：V1导联P波的病理终末电势（42%的患者）和PX波幅增加（39%的患者）。P波的病理变化随左心室肥厚和心力衰竭的发展而增加。与二尖瓣疾病相比，V1导联P波终末电势值为负且超过-0.03mm·s时应视为病理状态。
