توارث پذیری پارامترهای فیزیولوژیک قلب و عروق در یکصد و هفت جفت دختران 16 تا 19 ساله و مادران 32 تا 56 ساله در شهر شیراز بوسیله آنالیز الکتروکاردیوگرام و فشار خون مطالعه گردید. در این مطالعه سهم عوامل وراثتی در بعضی از شاخص های الکتروکاردیوگرام مانند فاصله (rp, interval)rp ، موج p، کمپلکس qrs ، فاصله qt تصحیح شده (qtc)، قطعه (rp-segment)rp ، تغییرات فشار خون و شاخص های آنت...
provided the original work is properly cited. CC Min et al. [1] investigated the effects of palonosetron, a second-generation 5-hydroxytryptamine-3 receptor antagonist, on corrected QT (QTc) intervals on electrocardiograms of patients undergoing laparotomies under sevoflurane anesthesia. Considering that prolongation of the QTc interval is associated with torsades de pointes, and palonosetron m...
OBJECTIVE Serotonin transporter gene polymorphism (5-HTTLPR polymorphism) predicts the degree of structural and functional connectivity in the brain, and less consistently the degree of vulnerability for anxiety and depressive disorders. It is less known how 5-HTTLPR polymorphism influences on the coupling between brain and neuronal cardiovascular control. The present study demonstrates the imp...
BACKGROUND Considerable interest exists in the identification of genetic modifiers of disease severity in the long-QT syndrome (LQTS) as their identification may contribute to refinement of risk stratification. METHODS AND RESULTS We searched for single-nucleotide polymorphisms (SNPs) that modulate the corrected QT (QTc)-interval and the occurrence of cardiac events in 639 patients harboring ...
Antipsychotic (AP) drugs have the potential to cause prolongation of the QT interval corrected for heart rate (QTc). As this risk is dose-dependent, it may be associated with the number of AP drugs concurrently prescribed, which is known to be associated with increased cumulative equivalent AP dosage. This study analysed whether AP dose mediates the relationship between polypharmacy and QTc int...
