Introduction to cardiac electrophysiology and assessment of sinus node and atrio-ventricular conduction

Autor: Uwanuruochi K, Ruchit S, Kokane HT

Publikováno v: Ibom Medical Journal, Vol 17, Iss 3 (2024)

Background: Interest in cardiac electrophysiology is increasing in sub-Saharan Africa, but the interpretation of results is poorly understood. Cardiac electrophysiology is the study of electrical activity of the heart by virtue of catheters that are

Publikováno v: Frontiers in Pediatrics, Vol 10 (2022)

Background:Sinus node dysfunction (SND) and atrial tachyarrhythmias frequently co-exist in the aging patient with congenital heart disease (CHD), even after surgical correction early in life. We examined differences in electrophysiological properties

Ultrastructure of primary pacemaking cells in rabbit sino‐atrial node cells indicates limited sarcoplasmic reticulum content

Autor: Ramesh Iyer, Oliver Monfredi, Manuela Lavorato, Mark Terasaki, Clara Franzini‐Armstrong

Publikováno v: FASEB BioAdvances, Vol 2, Iss 2, Pp 106-115 (2020)

Abstract The main mammalian heart pacemakers are spindle‐shaped cells compressed into tangles within protective layers of collagen in the sino‐atrial node (SAN). Two cell types, “dark” and “light,” differ on their high or low content of i

Sudden Death without a Clear Cause after Comprehensive Investigation: An Example of Forensic Approach to Atypical/Uncertain Findings

Autor: Simone Grassi, Mònica Coll Vidal, Oscar Campuzano, Vincenzo Arena, Alessandro Alfonsetti, Sabina Strano Rossi, Francesca Scarnicci, Anna Iglesias, Ramon Brugada, Antonio Oliva

Publikováno v: Diagnostics, Vol 11, Iss 5, p 886 (2021)

Sudden death (SD) is defined as the unexpected natural death occurred within an hour after the onset of symptoms or from the last moment the subject has been seen in a healthy condition. Brugada syndrome (BrS) is one of the most remarkable cardiac ca

Heart Rate Fragmentation as a Novel Biomarker of Adverse Cardiovascular Events: The Multi-Ethnic Study of Atherosclerosis

Autor: Madalena D. Costa, Susan Redline, Roger B. Davis, Susan R. Heckbert, Elsayed Z. Soliman, Ary L. Goldberger

Publikováno v: Frontiers in Physiology, Vol 9 (2018)

Background: A major objective of precision medicine is the elucidation of non-invasive biomarkers of cardiovascular (CV) risk. Recently, we introduced a new dynamical marker of sino-atrial instability, termed heart rate fragmentation (HRF), which out
