Electrogram (EGM) annotation during VT is challenging due to complexity of EGMs and difficulty in distinguishing far-field near-field (NF) EGMs. EGM frequency increases with greater proximity the recording electrode. The prognostic value high-frequency at critical ablation sites unknown. utility recently developed algorithms annotate local 3D mapping (Ensite X, Abbott, Inc.) absence high for ma...

Abstract Introduction Chlorinated paraffins (CPs) are important additives in a variety of chemical processing. Based on the lengths carbon chains, CPs classified into short-chain (SCCPs, C10-13), medium-chain (MCCPs, C14-17) and long-chain (LCCPs, C18-30) with chlorine content ranging from 30%-70%. SCCPs were listed persistent organic pollutants (POPs) by Stockholm Convention due to its toxicit...

Objectives Reverse transcriptase PCR (RT-PCR) is considered the gold standard in diagnosing COVID-19. Infected healthcare workers do not go back to work until RT-PCR has demonstrated that virus no longer present upper respiratory tract. The aim of this study determine most efficient time perform prior workers’ reincorporation. Materials and methods This a cohort with RT-PCR-confirmed Data were ...
