The electrocardiographic signs used to diagnose myocardial disease are nonspecific. Therefore, it would seem to be of significance, that, in nine myocarditis children with proved viral infections (6 under 1 year of age), there was a constant electrical abnormality. Eight of the nine had abnormally wide spatial QRS-T angles. Recordings were made before onset of therapy and were repeated frequently during both the acute and convalescent phases of the illnesses. It was found that the return to a normal angle coincided with the disappearance of cardiac disease. Other findings were variable. The regularity with which an abnormal spatial QRS-T angle was detected in our children with viral myocarditis made this finding a valuable and dependable tool for detection and evaluation of their disease.
