Association of premature ventricular complex burden with elevated left ventricular filling pressure.

Background: Premature ventricular contraction (PVC) is considered one of the most common arrhythmias in clinical practice. The aetiology of PVC is still unclear, however increased sympathetic activity, electrolyte misbalance and cardiomyopathies are considered the main causes of PVCs. In this study we were trying to find out whether there was any association between PVC burden and elevated left ventricular (LV) filling pressure.
