In addition to the changes demonstrated in this electrocardiogram, pulmonary embolism may cause atrial flutter or fibrillation, right ventricular premature beats, ventricular fibrillation, right bundle branch block (complete or incomplete) or less marked right ventricular conduction delay, right ventricular hypertrophy, ST-segment elevation, a long QT interval, and pulseless electrical activity (1-7) (Table).
This right ventricular hypertrophy may be due to the decrease in the cross sectional area of the pulmonary circulation, which exacerbates regional alveolar hypoxia and leads to a downward spiral of increased pulmonary vascular resistance, increased work of the right ventricle, more hypoxia and on and on.
Cardiac catheterization, 2-dimensional and Doppler echocardiography, VCG by Mcfee-Parungao (VCG) and electrocardiography were used to establish PAH and right ventricular hypertrophy (RVH).
The differential diagnosis of tall R waves in these leads includes right ventricular hypertrophy, ventricular septal hypertrophy, posterior myocardial infarct, right bundle branch block, ventricular preexcitation of the Wolff-Parkinson-White type, Duchenne's muscular dystrophy, dextrocardia and/or rightward displacement of the cardiac apex, and a normal variant (diagnosis of exclusion) (1).
