METHOD OF DIFFERENTIAL DIAGNOSIS OF ARRHYTHMIAS IN ADOLESCENTS WITH RESPIRATORY TUBERCULOSIS Russian patent published in 2024 - IPC A61B5/02 A61B5/205 A61B5/349 G01N33/50 G01N33/72 G01N33/82 G01N33/90 

FIELD: medicine; cardiology and phthisiology.

SUBSTANCE: invention can be used for the differential diagnosis of arrhythmias in adolescents with respiratory tuberculosis. When carrying out anti-tuberculosis therapy, an ECG is performed, and when a prolongation of the QTc interval > 460 ms is recorded against the background of tachycardia, a clinical blood test is performed to monitor the level of haemoglobin, serum iron, folic acid, potassium and sodium. When the level of haemoglobin decreases below 115 g/l, serum iron below 9.0 mcmol/l in girls and below 11.6 mcmol/l in boys and there are no deviations from the age norm in terms of folic acid, sodium and potassium, arrhythmia caused by iron deficiency anaemia is diagnosed. When the level of haemoglobin decreases below 115 g/l, serum iron below 9.0 mcmol/l in girls and below 11.6 mcmol/l in boys, folic acid below 3.1 ng/ml, and there are no deviations from the age norm in the indicators sodium and potassium, arrhythmia caused by iron deficiency and folate deficiency anaemia is diagnosed.

EFFECT: method allows to select an effective treatment regimen for the causes of arrhythmia in adolescents with respiratory tuberculosis by increasing the reliability and efficiency of arrhythmia diagnostics by assessing the totality of the most significant indicators.
