Objectives: Electromagnetic fields (EMF) may cause malfunctions in electronic devices, in particular in active implantable medical devices (AIMD), along with discomfort or health hazards to users. The use of AIMD by workers is increasing (especially cardiac pacemakers, implantable cardioverter defibrillators and wearable insulin infusion pumps). Electromagnetic fields may be much stronger in the working environment than applied in basic immunity tests of AIMD (based on EN 60601- 1-2:2015 and EN 50527-1:2016). Read More

During the past years, the industry and most transcatheter aortic valve operators have focused on reduction of paravalvular leaks rather than on the reduction of permanent pacemakers (PPM). However, since indication for transcatheter aortic valve implantation (TAVI) is moving toward a healthier and younger patient population, new PPMs may become more of an issue. Certain factors such as pre-existing conduction disorders or anatomical features cannot be changed. Read More

Background: Remote Monitoring (RM) has been introduced for several years and nowadays most pacemakers are equipped with such a technology. RM can provide early detection of high atrial rate episodes (AHREs) onset and enable prompt medical intervention. However, there are still little data on the clinical reactions triggered by the AHRE detected by RM of pacemaker recipients and on their possible benefit on patients' outcome. Read More

Permanent cardiac pacemakers have traditionally comprised a surgically implanted subcutaneous pulse generator affixed to at least one transvenous pacing lead. Despite technological advances, implant-related complications and transvenous-lead failure rates have remained high. The Micra Transcatheter Pacing System is a miniaturized single chamber pacemaker that is implanted directly into the right ventricle, eliminating the subcutaneous pocket and creating a leadless pacemaker system.

Cardiac resynchronization pacing therapy (CRT) can be a potentially effective modality to delay the need for heart transplantation and improve the clinical status among patients with heart failure. Unfortunately, published guidelines and studies with an over-reliance on ejection fraction (EF) and QRS duration as markers for efficacy are frequently not applicable to the ever-growing number of adults with repaired congenital heart defects (CHD), some with systemic anatomical right ventricles as well as pre-existing pacemakers. In this issue of Pacing and Clinical Electrophysiology, Moore et al introduce a novel pre-selection screening process to optimize paced contractility among patients with repaired CHD and systemic right ventricles.

Artificial implantable pacemakers have long been a challenge to neurosurgeons seeking to perform advanced diagnostic imaging on their patients. Unfortunately, while the use of implantable pacemakers has been a life-saving advance for those with cardiac arrhythmias, they also often prevent these patients from undergoing magnetic resonance imaging (MRI). There have been multiple reported cases of pacemaker failure in the context of MRI use. Read More

Patients with a single ventricle have complex anatomy that requires staged palliation which is usually the Fontan procedure. This procedure has undergone a lot of modifications to improve hemodynamics. Despite these efforts, sinus node dysfunction (SND) and bradyarrythmias are still common complications after Fontan operation, therefore there is a need of pacemakers implantation. Read More

Introduction: Heart failure is a common finding in patients with pacemakers implanted for bradycardia, with cross-sectional and longitudinal studies contributing to the growing consensus that right ventricular pacing can cause adverse cardiac remodeling and left ventricular systolic dysfunction increasing the risk of hospitalization and death. An unselected approach using cardiac resynchronization therapy from the time of first implant in patients with heart block has produced equivocal results. Contemporary research has therefore begun to focus on the stratification of patients' risk of pacemaker-associated impairment to permit focused, personalized management. Read More

Parylene C is a promising material for constructing flexible, biocompatible and corrosion-resistant microelectromechanical systems (MEMS) devices. Historically, Parylene C has been employed as an encapsulation material for medical implants, such as stents and pacemakers, due to its strong barrier properties and biocompatibility. In the past few decades, the adaptation of planar microfabrication processes to thin film Parylene C has encouraged its use as an insulator, structural and substrate material for MEMS and other microelectronic devices.

Patients with focal temporal lobe seizures often experience transient episodes of impaired awareness with behavioral arrest, but the precise mechanism remains unknown. The Network Inhibition Hypothesis attributes these deficits to a loss of cholinergic input to the cortex. This is presumed to result from increased activation of inhibitory regions that suppress subcortical arousal, giving rise to cortical delta wave activity. Read More
