| Abstract [eng] |
Asymptomatic supraventricular tachycardia is a recurrent, seizure-like episode of heart palpitations of more than 100 bpm with triggers formed in the atria. The most common asymptomatic supraventricular tachyarrhythmia is atrial fibrillation. Worldwide, atrial fibrillation affects 2-4% of adults and the incidence of atrial fibrillation is expected to increase 2.3-fold due to increasing life expectancy and early diagnosis. 50-87% However, this condition may be asymptomatic, so the exact number of cases remains unknown. Atrial fibrillation is associated with a 5-fold increased risk of developing ischemic stroke and heart failure. In this work, we investigate a clinical case of asymptomatic supraventricular tachyarrhythmia characterized by progressive heart failure. The patient visits the VUL SK admissions department at least once a year for symptoms of progressive heart failure - decreased exercise tolerance and general weakness. The patient does not experience arrhythmia and the normocystic form of persistent atrial fibrillation is recorded on the electrocardiogram. At 6 years, marked decreases in left ventricular ejection fraction and dilatation of the heart cavity were observed. Thus, in this work, we analyze the association between asymptomatic atrial fibrillation and the progression of heart failure and possible treatment tactics for controlling heart rate and rhythm. |
