ECG shows:
Sinus Tachycardia, 100/min, Right axis deviation.
Complete RBBB, QRS duration 0.15 second.
Dominant R wave in V1, deep S waves in lateral leads. Suggestive of RVH
Features of left atrial hypertrophy:

Combination of left atrial hypertrophy and right ventricular hypertrophy suggests mitral stenosis. This patient had mitral stenosis on the basis of rheumatic heart disease.
