The present study shows the ECG changes that attributed to the acute RV pressure loading states (Premature atrial contraction, right axis deviation, indeterminate axis, incomplete RBBB, late R in aVR, qR in V1) may be more prevalent in patients with chronic pressure loading states.
Clinical assessment of patients with possible PAH includes an electrocardiogram, which may show changes in the right ventricle, including right axis deviation, right atrial enlargement, and right ventricular hypertrophy, Dr.
ECG showed right axis deviation but no right or left ventricular hypertrophy.
ECG on lead I demonstrates right axis deviation along with a negative deflection of the P waves and QRS complexes.
The ECG changes associated with PE include sinus tachycardia (the most common abnormality), complete or incomplete right bundle branch block, a right ventricular strain pattern (T wave inversions in the right precordial leads [V1-4] [+ or -] the inferior leads [II, III, aVF]), a right axis deviation, or an SI QIII TIII pattern (a deep S wave in lead I, Q wave in III, and inverted T wave in III) (2).
