as it has proven the increase of mechanical strain could resulted to increase of bnp (protein brain natriuretic peptide) in blood stream of implanted patient pacemakers. we measured the bnp concentration in blood due to different mode and lead implantation location of pacemaker in the time period of three month. the aim of study was the investigation of change trend of bnp level after pacemaker...

BACKGROUND Magnetic fields may potentially interfere with the function of cardiovascular implantable electronic devices. Sterile magnetic drapes used to hold surgical instruments are often placed on the patient's thorax, and they are likely to interfere with the function of these devices. METHODS Thirty patients were recruited to compare a new prototype surgical magnetic drape (LT10G™ by Meno...

A pacemaker is a small battery operated device that helps the heart to beat in a regular rhythm. It contains a powerful battery, electronic circuits, and computer memory that jointly generate electronic signals. One of the main problems about pacemakers is their batteries. Since the capacity of the batteries is limited, it limits the pacemakers lifetime. The other method to power up the implant...

DOI: 10.5935/abc.20160144 67 year-old female patient, pacemaker user since 1983 due to complete atrioventricular block. Between 1991 and 2004, the patient underwent six surgeries. The first was to replace the batteries, and the others for electrode displacement, generator extrusion, and finally for endocarditis, when surgical extraction of the system and epicardial electrode implantation in the...

Hyperkalemia is a common clinical condition among heart failure patients especially if there coexisting older age, potassium-sparing medication, and renal insufficiency. Close follow-up titration of renin-angiotensin-aldosterone system inhibitors are essential to prevent the development hyperkalemia. It can also cause significant abnormalities in with cardiac implantable electronic devices (CIE...

The development of the implantable cardiac pacemaker nearly 60 years ago represented a paradigm shift in the control of potentially lethal heart rhythms and has revolutionized the lives of those at risk of sudden death from bradycardia. Subsequent technological developments have resulted in devices that offer additional benefits to patients, including defibrillation and resychronisation therapy...

BACKGROUND Widespread use of cardiovascular implantable electronic devices has inevitably increased the need for lead revision/replacement. We report our experience in percutaneous extraction of transvenous permanent pacemaker/defibrillator leads. METHODS Thirty-six patients admitted to our centre from September 2005 through October 2012 for percutaneous lead extraction were included. Lead re...

background: neonatal lupus erythematosus is an uncommon disease. congenital complete heart block (cchb) usually happens in neonates with maternal systemic lupus erythematosus. the most prevalent presentation of cchbis bradycardiathatcanbediagnosed through an electrocardiogram. case report: here in, we present the case of a full-term male neonate with gestational age of 37 weeks and birth weight...

Endurance athletes exhibit sinus bradycardia, that is a slow resting heart rate, associated with a higher incidence of sinus node (pacemaker) disease and electronic pacemaker implantation. Here we show that training-induced bradycardia is not a consequence of changes in the activity of the autonomic nervous system but is caused by intrinsic electrophysiological changes in the sinus node. We dem...

Normal heart rhythm (sinus rhythm) depends on regular activity of the sinoatrial node (SAN), a heterogeneous collection of specialized myocytes in the right atrium. SAN cells, in general, possess a unique electrophysiological profile that promotes spontaneous electrical activity (automaticity). However, while automaticity is required for normal pacemaking, it is not necessarily sufficient. Less...
