Aim: Premature ventricular complexes are one of the most common arrhythmias and, when not treated, can cause serious complications such as dilated cardiomyopathy and ventricular tachycardia. In our study, we investigated the relationship between QRS duration and symptoms in patients with idiopathic premature ventricles complex (IPVC). Material and Methods: This is a multicenter, cross-sectional study involving 242 consecutive patients with more than 1,000 idiopathic PVC and normal QRS duration in 24-hour Holter follow-up who attended cardiology clinics in 18 different centers between January 2019 and May 2019. The relationship between the QRS durations was investigated by dividing the patients into 2 groups as symptomatic (n: 128) and asymptomatic (n: 114). Result: The average age of 242 patients was 51 ± 13 and 52.4% (127) of them were male patients. In the symptomatic IPVC group, sinus QRS duration, PVC QRS duration, coupling interval, and prematurity index were statistically significantly higher than the asymptomatic IPVC group. In the multivariate logistic regression analysis, a significant relationship was found between the sinus QRS duration (odds ratio (OR) = 1.3, 95% confidence interval (CI) = 1.01-1.05, p = 0.002) and symptoms in patients with IPVC. In the ROC analysis performed to show the power of sinus QRS duration in predicting symptoms in patients with IPVC, Area Under Curve (AUC) value was found as = 0.547 95% CI: 0.454-0.640, p = 0.320 (Figure 1). Conclusion: In patients with IPVC; The prolonged sinüs QRS duration was found to be superior to other parameters in patients being symptomatic. |
