Introduction. The study of the external respiratory function (spirometry) is a generally recognized gold standard for the study of the respiratory system, mandatory for many pulmonary diseases. Global standards for the management of patients with bronchial asthma (GINA) and chronic obstructive lung disease define spirometry as the main method for assessing the effectiveness of treatment and determining the prognosis of these diseases. At the same time, the stress nature of the study and the tests performed during the study with inhaled adrenomimetics as bronchodilators can have a significant effect on the cardiovascular system of the patients being examined. Adrenomimetics are expected to cause an increase in heart rate and tachycardia-related arrhythmias – atrial fibrillation and similar conditions.

Objective: present a case of the “atypical” side effect of bronchodilator test during spirometry.

Results. The article presents a case of bigeminy, which developed as a side effect of a test with bronchodilators (salbutamol) during the study of the external respiratory function. This response to adrenergic drugs may be considered as atypical, since there is general agreement that tachycardia should prevent the development of ventricular bigeminy. The study was conducted on a patient with pneumofibrosis (pneumoconiosis), which developed as a result of long-term work in conditions of increased dustiness.

Conclusions. Cardiovascular pathology associated with pneumoconiosis may be considered a possible explanation for the development of bigeminy following salbutamol administration.

Keywords: functional diagnostics, spirometry, bronchodilator test, arrhythmia.
