ECG findings in which the P wave amplitude in leads II, III and/or aVF is greater than 2.5 mm.
An abnormal pattern seen on an electrocardiogram, associated with diffuse lung disease and acute pulmonary embolism; it consists of tall peaked P waves in the inferior leads and P axis to the right of + 70°.
Reflects right atrial overload (right heart strain) and is a marker of disease processes that involve stress to the right heart circulation.
Correlation with echocardiographic findings is poor and ECG patterns of right axis deviation, S1S2S3, S1Q3 and P wave axis are more sensitive indicators of right heart strain.
