Popis: The association of atrial fibrillation (AF) with complete atrioventricular block (CAVB) is a common clinical feature in elderly patients. It is characterized by the loss of specific symptoms of AF (palpitations, intermissions); in the first place may come CAVB symptoms: dizziness, Morgagni–Adams–Stokes (MAS) attacks. Aim. The article objective is to illustrate the dynamic changes in the course of AF with the development of CAVB on the example of a clinical case and to discuss the difficulties in timely diagnosis and therapy correction. Case presentation. A 75-year-old male was diagnosed with a rapid ventricular response form of AF. The onset of CAVB caused the transition from rapid ventricular response form of AF to slow ventricular response form, which was initially accompanied by a subjective improvement in the patient’s condition. As the disease progressed, the patient’s condition worsened due to the development of MAS attacks. The elderly patients with a permanent form of AF require constant cardiac monitoring by an experienced specialist who has appropriate vigilance in management of patients with arrhythmias, awareness about possible concomitant conduction disorders. This provides comprehensive cardiac support, including timely pacemaker implantation which gives more options for AF symptoms monitoring and heart rate control, has a positive modifying effect on drug therapy. Conclusions. Changes in the clinical picture of AF after development of CAVB can lead to late diagnosis of CAVB, inadequate therapy and untimely pacemaker implantation, as a consequence, to progression of concomitant pathology and the development of life-threatening complications, as in our clinical case.
