Experimental analysis and computational modeling of interburst intervals in spontaneous activity of cortical neuronal culture [PDF]
, 2011 Rhythmic bursting is the most striking behavior of cultured cortical networks and may start in the second week after plating. In this study, we focus on the intervals between spontaneously occurring bursts, and compare experimentally recorded values with

Early experience with permanent pacemaker implantation at a tertiary hospital in Nigeria
The Pan African Medical Journal, 2020 INTRODUCTION: Artificial pacemakers generate electrical impulses and regulate the heart´s conduction system. They are often used to treat individuals with bradycardia. Permanent pacemaker implantation is a lifesaving procedure especially in patients with

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]
, 1955 Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Twenty years' use of expanded polytetrafluoroethylene sheet for an artificial cardiac pacemaker
Clinical Case Reports, 2021 Physicians can prolongedly use expanded polytetrafluoroethylene sheets for fixation of artificial cardiac pacemakers to avoid pacemaker lead displacement. The sheets can also be used to prevent implant rejection in patients with metal allergies.
