Detecting arrhythmia The electrical system of the heart This is the first in a series of articles intended to assist in identifying and detecting arrhythmias in the heart using emka TECHNOLOGIES ecgAUTO software. We will begin this series by introducing – in very general terms – the electrical system of the heart, followed by a […]
Arrhythmia detection: Part 2 – Identifying premature ventricular contractions with ecgAUTO
Detecting arrhythmia Identifying premature ventricular contractions with ecgAUTO This document is a guide to help identify and quantify Premature Ventricular Contractions (PVC’s) in ecgAUTO. These guidelines will allow for consistent data interpretation for this type of arrhythmia. To learn more, read also: Detecting arrhythmia : Part 1 – The electrical system of the heart
Isolated heart techniques
Isolated heart techniques Isolating the heart is an ex vivo technique used to investigate small mammalians cardiac function, in health and disease, or following drug challenges. Nowadays, both Langendorff heart and working heart techniques are commonly used. But what is the difference between both techniques? This guide includes: A short video introducing both methods Diagrams […]

Cardiotoxicity
Cardiotoxicity studies Cardiotoxicity can be described as dysfunction of the heart stemming from exposure to drugs, pollutants, or other toxins. The irreversible cardiac dysfunction and development of heart failure is characterized by electrophysiological, morphological, and biochemical alterations. Cardiotoxicity is often associated with a decline in left ventricular ejection fraction (LVEF) and autonomic disbalance. Drug-induced cardiotoxicity […]
Vascular Biology
Vascular Biology Vascular biology implies understanding mechanisms involved in vascular tone, hemostasis, thrombosis and pathobiology of ischemic syndrome, remodeling, and plaque formation. It involves functional assessment of endothelial and smooth muscle cells in the vascular system. The major regulator of vascular homeostasis is the endothelium, which is a thin layer of cells that line the […]
