Peculiarities of cardiac performance in children with bronchial asthma against chronic tonsillitis.
Acomparativeassessmentofcardiacperformancebythedataofclinical-instrumentalexaminationof 50 patientsaged 5-15 yearswithpersistingformofpartially-controlledatopicbronchialasthmain the period between the attacks of the disease was made. Children were divided into two groups depending on presence of concomitant chronic tonsillitis (18 patients)or absence of the latter (32 patients).
