Electrocardiograms (ECGs) in patients with pulmonary arterial hypertension (PAH) often reveal abnormal changes in cardiac structure and function, aiding in diagnosis and disease monitoring. These alterations may include right ventricular hypertrophy, right bundle branch block (RBBB), and pulmonary P waves.

Upon closer examination, right ventricular hypertrophy is one of the most frequent findings in PAH. The ECG may demonstrate an R/S ratio greater than 1 in lead V1 or a combined amplitude of RV1+SV5 exceeding 1.05 millivolts. RBBB is also a common ECG finding, presenting with a prolonged QRS duration and an rSR’ or M pattern in lead V1. Pulmonary P waves, indicative of elevated right atrial pressure, are characterized by P wave amplitudes in leads II, III, and aVF that are equal to or greater than 0.25 millivolts. These ECG changes typically become more pronounced with increasing severity of PAH.

For individuals suspected of PAH, it is advised to seek medical attention without delay and to undergo a comprehensive ECG examination. ECG results should be interpreted by a qualified physician to ascertain the need for further diagnostic testing and treatment. Throughout the treatment process, patients should adhere to their physician’s recommendations and undergo regular ECG monitoring to track disease progression.
