Cardiac pacemakers in paediatric patients: a qualitative study of patient and parental experience
The aim of the study was to explore the experience of having a pacemaker as a child or young person and the experience of their parent in caring for them. Due to lack of research, very little is known about the impact that having a pacemaker has on children and their parents. However, evidence from …

In vivo mechanical loading conditions of pectorally implanted cardiac pacemakers : feasibility of a force measurement system and concept of an animal-human transfer function
… vivo mechanical loading on pectorally implanted pacemakers, to compare differences in mechanical loading experienced by pacemakers in different pectoral implant positions (i.e. sub-muscular and sub-coetaneous) and to formulate a concept of an interspecific transfer function for predicting the in …

The Effect of Programmed Instruction about Pacemakers given in the Hospital Setting on the Immediate and Delayed Retention of Information on Patients with Permanent Cardiac Pacemakers
… hospitalized for initial placement of permanent cardiac pacemakers, was studied. A programmed instructional test was prepared by the investiga- tors for this population. The question under study was, does programmed instruction for pacemaker patients affect immediate and delayed recall of …

An Effective Transcutaneous Energy Transfer (TET) System for Artificial Hearts
… medical devices such as cochlear implants, cardiac pacemakers and artificial heart pumps, consume electrical energy for the lifetime of the patient. The method of power delivery in these devices is principally dependent on their power requirements. Low power implantable devices, such as …

The Relationship between Ephaptic Coupling and Excitability in Ventricular Myocardium
… if conduction decreases, excitability decreases) Cardiac sodium channels are densely expressed in the intercalated disc within the perinexus, which is two orders of magnitude narrower than bulk extracellular interstitium. The biphasic relationship between conduction and perinexus is …
