| Popis: | To the Editor: We read with great interest the article by Hwang et al.1) who presented important data for the clinical characteristics and features of idiopathic ventricular premature complexes (VPC). In their well-written manuscript, the authors reported that VPC frequency was higher in women than in men and the main electrocardiography morphology of VPC was the left bundle branch block pattern, inferior axis and late precordial R-wave transition. These findings are very helpful in demonstrating that non-western communities are consistent with the traditional knowledge in terms of demographic and clinical VPC features. However, we would like to contribute a different view to the study. It is known that some factors, such as anxiety, increased sympathetic activation, tabacco or alcohol usage, anemia and thyroid function disorders etc., may affect the VPC frequency.2),3) When assessing the VPC frequency and its outcomes, multiple factors should be taken into consideration. It would have been better if the authors had mentioned about thyroid and complete blood count results. But the main point that we want to emphasize is the sympathetic activity. Although sympathetic activity has an effect on VPC frequency (especially in women), it is very difficult to determine this activity in retrospective studies. However, Aparci et al. suggested a new scoring system, "Sympathetic activity index", which is based on scores of heart rate, body mass index and systemic blood pressure.4) This index seems to be useful in grading sympathetic drive. Also, the already mentioned parameters are appropriate for retrospective studies and adding this score would make the study more precise. |
