dc.description.abstract | In patients with premature ventricular contractions, the main cause of cardiomyopathy associated with arrhythmia is considered to be a large number of premature ventricular contractions. The width and fragmentation of QRS complex, morphology, prematurity index, polymorphism and some other characteristics may also play a role. Previously, the hemodynamic features of several variants of premature ventricular contractions such as allorhythmia (bigeminy), paired and interpolated premature ventricular contractions and ventricular parasystole have not been evaluated. We perform examples of these types of ventricular arrhythmias with assessment of their hemodynamic properties using the original method of accurate determination of systolic, diastolic and pulse blood pressure during each beat of the heart “beat to beat”. The main properties of premature ventricular complexes have been demonstrated: a marked decrease in systolic and an increase in diastolic blood pressure. As an example, in ventricular parasystole these indicators have been shown to be dependent on the clutch interval of premature ventricular contractions: the shorter it is, the more advanced the changes. Bigeminy and interpolated premature ventricular contractions appears to be hemodynamically unfavorable. | en_GB |
