Provides a clinical example of electrocardiographic findings in a patient with pulmonary hypertension secondary to congenital heart disease.
Provides context for ECG interpretation in PH with PDA; leaves open generalizability beyond this single case.
Figure 1 shows the electrocardiogram of a 60-year-old woman who initially presented in the third decade of life with mild symptoms of dyspnoea, reduced exercise capacity and fatigue. Clinical signs included cyanosis and clubbing, right ventricular heave, palpable and loud pulmonary second sound, and a soft pansystolic murmur. Echocardiography confirmed a patent ductus arteriosus and evidence of pulmonary hypertension with right ventricular hypertrophy (RVH), significant tricuspid regurgitation and pulmonary regurgitation.
