SUMMARY. Ambulatory ECG monitoring is widely used in clinical practice; it allows for continuous and prolonged observation of the patient's heart rhythm in their natural environment. Continuous, long-term monitoring is more likely to detect parasystole, which may go unnoticed during short-term recordings. The activity of the paracenter can be assessed by the classic ECG criteria for parasystole: 1) variable coupling interval; 2) mathematically related interventricular intervals; 3) presence of ventricular fusion. The appropriate tools available in the arsenal of modern programs for analyzing long-term ECG recordings, as well as options for statistical data presentation (trends, graphs, tables), allow for high-quality differentiation of arrhythmias and visualization of results.
The aim – to summarize the possibilities of Holter ECG for the diagnosis of parasystoles and to highlight our own clinical observations regarding this rhythm disorder.
Material and Methods. We evaluated parasystole in a cohort of 95 consecutive cases diagnosed by Holter ECG monitoring using the multifunctional electrocardiographic system “ECG-pro” (IMESC).
Results. The electrocardiographic criteria for parasystole and the possibilities of its diagnosis using Holter ECG are highlighted. The diagnostic search and options for statistical presentation of results using the software of modern programs for long-term ECG recording are described.
Conclusions. Holter ECG monitoring is one of the most common and highly informative modern methods of functional diagnostics for detecting arrhythmias, their quantitative and qualitative analysis, and assessing the effectiveness and safety of treatment. The software of modern devices for long-term ECG recording has a number of appropriate tools and methods of statistical data presentation used for analysis, visualization of the results obtained and formation of correct conclusions.
