the overall rate of atrial pacing lead dislodgement is estimated to be about 3%. these leads are generally repositioned via a second operation through opening the pacemaker pocket. some operators have introduced percutaneous techniques using snare system or deflectable catheters for this purpose. in this article we present our experience with five cases of percutaneous lead repositioning. three...

Athlete-environment interactions are crucial factors in understanding the regulation of exercise intensity in head-to-head competitions. Previously, we have proposed a framework based on the interdependence of perception and action, which allows us to explore athletic behavior in the more complex pacing situations occurring when athletes need to respond to actions of their opponents. In the pre...

We report a case of a 85-year old woman with a preexisting Transcatheter Pacing System (TPS) (Micra™ VR, Fa. Medtronic, Inc., Minneapolis, MN, USA) undergoing several external electrical cardioversions (CV) for symptomatic persistent atrial fibrillation (persAF). Due to bradycardia in the setting of atrial fibrillation a right apical TPS implantation was performed earlier. Four weeks prior to p...

Age is a risk factor for both cardiovascular disease and cancer, as such radiation oncologists frequently see number of patients with cardiac implantable electronic devices (CIEDs) receiving proton therapy (PT). CIED malfunctions induced by PT are nonnegligible can occur in passive scattering pencil beam scanning modes. In the absence an evidence-based protocol, authors emphasise that this pati...

Objectives: Postoperative atrial fibrillation (POAF) is a frequent complication following cardiac surgery. This study examined the safety and efficacy of new DefiPaceTM system consisting two bi-atrial temporary pacing cardioversion electrodes, ventricular electrode device (combined external pacemaker cardioverter) for low-energy cardioversion. Methods: The electrodes were placed on left right a...

Right ventricular (RV) pacing has been the mainstay of bradycardia therapy for several decades. However, recognition deleterious effects RV led to search more physiologic forms pacing. Physiological Pacing, including His bundle (HBP) and left branch (LBBP), recently shown have better synchronization ventricle, potentially reduces heart failure1,2. high-resolution activation patterns during diff...

In light of evolving pacemaker technology and increasing interest in multisite pacing, the Committee on the Development of Position Statements (CDPS) of the North American Society of Pacing and Electrophysiology (NASPE) created an ad hoc Pacemaker Mode Code Task Force in April 2001 under the chairmanship of David L. Hayes, MD, for the purpose of bringing the NASPE/British Pacing and Electrophys...

The reproducibility of clinical and hemodynamic events during two successive pacing periods separated by a 20-minute interval was evaluated in 33 patients with stable angina pectoris. Continuous pacing with stepwise increase in pacing rate was assessed in 19 patients and discontinuous pacing in which pacing was temporarily interrupted at each rate was evaluated in the other 14 patients. During ...
