Systolic time intervals (STI) were measured non-invasively in 12 controls and 10 cases each with fever due to acute malaria, acute viral infection, typhoid fever, and fever induced by T.A.B. vaccine. Apart from tachycardia, no clinical feature of impaired cardiovascular function was present in any of the febrile cases. Abnormalities of STI were found in all febrile groups. Of the total 40 cases, only 18 showed normal STI, 2 cases showed decreased PEP/LVET indicative of hyperdynamic circulatory state, and 20 cases showed increased PEF/LVET suggesting the presence of subclinical impairment of myocardial function.
