Acute Isolation of Cells from Murine Sino-atrial Node
Bio-Protocol, 2020 The cardiac conduction system allows the synchronized propagation of electrical activity through heart muscle. This is initiated by the spontaneous activity of the specialized pacemaker cells of the sino-atrial node (SAN).

The effect of aging on the specialized conducting system: a telemetry ECG study in rats over a 6 month period. [PDF]
PLoS ONE, 2014 Advanced age alone appears to be a risk factor for increased susceptibility to cardiac arrhythmias. We previously observed in the aged rat heart that sinus rhythm ventricular activation is delayed and characterized by abnormal epicardial patterns ...

An introduction to mathematical and numerical modeling in heart electrophysiology [PDF]
, 2016 The electrical activation of the heart is the biological process that regulates the contraction of the cardiac muscle, allowing it to pump blood to the whole body. In physiological conditions, the pacemaker cells of the sinoatrial node generate an action

Numerical simulation of electrocardiograms for full cardiac cycles in healthy and pathological conditions [PDF]
, 2015 This work is dedicated to the simulation of full cycles of the electrical activity of the heart and the corresponding body surface potential. The model is based on a realistic torso and heart anatomy, including ventricles and atria.

Towards the Emulation of the Cardiac Conduction System for Pacemaker Testing [PDF]
arXiv, 2016 The heart is a vital organ that relies on the orchestrated propagation of electrical stimuli to coordinate each heart beat. Abnormalities in the heart's electrical behaviour can be managed with a cardiac pacemaker. Recently, the closed-loop testing of pacemakers with an emulation (real-time simulation) of the heart has been proposed.

Advanced Engineering Materials, EarlyView.This study demonstrates the feasibility of fabricating free‐standing carbon paper electrodes by electroplating and galvanic replacement. Nanostructured AgM (M = Au, Pt, Pd) bimetallic catalysts are directly grown on the electrode substrate, which exhibit good performance for glycerol electrolysis, a sustainable approach for the co‐production of green ...
