Summary
There is a close correlation between radiocardiographic picture, pulmonary circulation time (PCT), and the clinico-radiologic grades of bilharzial cor pulmonale. In grade I both PCT and radiocardiogram were normal. On the other hand, radiocardiography in cases of grade II revealed an increase in the duration of the descending limb of the R wave as well as moderate prolongation of PCT. Lastly, grade III was characterized by marked prolongation of PCT, together with a large R wave in the radiocardiogram due to prolongation of both the ascending and descending limbs of this wave.
