Synchronization of the cardiac pacemaker model with delayed pulse-coupling [PDF]

arXiv, 2011
We consider the integrate-and-fire model of the cardiac pacemaker with delayed pulsatile coupling. Sufficient conditions of synchronization are obtained for identical and non-identical oscillators.

A Beating‐Heart Procedure with Soft Robotic Guidance

Advanced Robotics Research, EarlyView.
Robot‐assisted pacemaker lead placement through the coronary sinus enabled cardiac pacing in multiple in vivo studies. When compared with conventional clinical tools, the robot reduced procedural time, duration of harmful radiation exposure, and the possibility of tissue damage.

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.

Spatial heterogeneity enhances and modulates excitability in a mathematical model of the myometrium [PDF]

, 2013
The muscular layer of the uterus (myometrium) undergoes profound changes in global excitability prior to parturition. Here, a mathematical model of the myocyte network is developed to investigate the hypothesis that spatial heterogeneity is essential to ...
