background: the advancement of technology in recent decades has been lead to use the electrophysiology cardiac devices. although these devices are used increasingly, but the frequency of subclinical infection is unknown. we investigate bacterial infections due to implantable cardioverter defibrillator (icds) in patients with endocarditis. m aterials and methods: population of the study was cons...

a 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. he finally was diagnosed as having twiddler's syndrome. the patient had a pulse rate of 36/min and cannon waves in the neck veins. chest radiography showed a dislodged pacing lead completely wrapped around the pulse...

background: permanent pacemakers provide effective relief of symptoms and are life-saving in patients with symptomatic heart block. implantable cardioverter defibrillators (icd) are also increasingly recognized as life-saving tools in various groups of patients with malignant ventricular tachyarrhythmias. methods: as part of the “world survey on pacemaker and icd implantations”, a survey of all...

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: 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...

Introduction: Beat-to-beat variation in heart rate shows a complex dynamics, and this complexity is changed during systemic inflammatory response syndrome (e.g. sepsis). It is not known whether or not cardiac pacemaker dynamical rhythm is affected by sepsis. The aim of this study was to investigate heart rate dynamics of isolated heart as well as expression of pacemaker channels (HCN) in a r...

background : patients undergoing pacemaker implantation often experience anxiety and fear. as such, studies have focused on the mechanisms that relieve the negative emotions caused by the intervention. continuous nursing is a safe and effective nursing mode. in this study, continuous nursing intervention was provided for elderly patients undergo-ing pacemaker implantation and an empirical inves...

conclusions in the children in this study, pacemaker accelerometers failed to meet physiological demands. results basal heart rates, maximal heart rates, and exercise tolerance were significantly lower in the children with pacemakers. age, sex, and body mass index had no effect on the heart rate slope during the exercise test. there was no significant difference between epicardial and endocardi...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...
