An analysis of symptoms in patients with permanent ventricular Pacemakers
Journal of clinical epidemiology, 1992Co-Authors: Harold Smulyan, Sakti Mookherjee, Harvey A. Taub, Robert A. WarnerAbstract:Abstract The prevalence and severity of symptoms of the “Pacemaker syndrome” were investigated in 64 patients with VVI Pacemakers and compared, in the same patients, to a series of control symptoms, unrelated to Pacemaker function. Symptoms were also compared in patient groups unlikely to have the “Pacemaker syndrome” (atrial fibrillation), most likely to have such symptoms (retrograde atrial activation) and in an intermediate group (competitive paced and sinus rhythms). There was a linear relationship between the frequency and severity of “Pacemaker” symptoms and control questions in all groups and no preponderance of “Pacemaker” symptoms in any group. The study provides an estimate of the number and severity of symptoms in patients with VVI Pacemakers, demonstrates the non-specificity of the “Pacemaker syndrome” and shows no evidence of a sub-clinical “Pacemaker syndrome” in the patients observed.

trends in permanent Pacemaker implantation in the united states from 1993 to 2009 increasing complexity of patients and procedures
Journal of the American College of Cardiology, 2012Co-Authors: Arnold J Greenspon, Jasmine D Patel, Edmund Lau, Jorge A Ochoa, Daniel R Frisch, Behzad B Pavri, Steven M KurtzAbstract:Objectives This study sought to define contemporary trends in permanent Pacemaker use by analyzing a large national database. Background The Medicare National Coverage Determination for permanent Pacemaker, which emphasized single-chamber pacing, has not changed significantly since 1985. We sought to define contemporary trends in permanent Pacemaker use by analyzing a large national database. Methods We queried the Nationwide Inpatient Sample to identify permanent Pacemaker implants between 1993 and 2009 using the International Classification of Diseases-Ninth Revision-Clinical Modification procedure codes for dual-chamber (DDD), single-ventricular (VVI), single-atrial (AAI), or biventricular (BiV) devices. Annual permanent Pacemaker implantation rates and patient demographics were analyzed. Results Between 1993 and 2009, 2.9 million patients received permanent Pacemakers in the United States. Overall use increased by 55.6%. By 2009, DDD use increased from 62% to 82% (p Conclusions There is a steady growth in the use of permanent Pacemakers in the United States. Although DDD device use is increasing, whereas single-chamber ventricular Pacemaker use is decreasing. Patients are becoming older and have more medical comorbidities. These trends have important health care policy implications.

The Pacemaker Syndrome — A Matter of Definition
The American journal of cardiology, 1997Co-Authors: Kenneth A Ellenbogen, David M Gilligan, Mark A Wood, Carlos Morillo, S. Serge BaroldAbstract:Pacemaker syndrome is an iatrogenic disease that is often underdiagnosed. We propose that Pacemaker syndrome represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode. Clinicians implanting and programming Pacemakers should attempt to optimize AV synchrony to prevent the occurrence of Pacemaker syndrome.

MRI Conditional Pacemakers
2014Co-Authors: Johnson Francis, Kenneth A EllenbogenAbstract:Conventionally, magnetic resonance [MR] imaging is an absolute contraindicationfor those with an implanted Pacemaker [1].This represents a significant clinical problem as several studies have shown approximately 75% of patients with Pacemakers will have an indication for an MRI scan.  Patients over the age of 65 are twice as likely to require an MRI and 80% of Pacemaker patients are over the age of 65. MR imaging is an important source of information for neurological disorders and several soft tissue abnormalities. Hence denying this important diagnostic modality for those with an implanted Pacemaker and other cardiac implantable electronic devices [CIED] is a tremendous clinical problem both because of concerns about MRI signals interfering with the function of the Pacemaker and the Pacemaker in turn interfering with the MR images.There are a number of potential effects of MRI signals on cardiac Pacemakers and leads. MRI signals can interfere with the function of the Pacemaker and the leads as a result of the static magnetic field, the gradient magnetic field, the modulated radiofrequency field and the combined field effects.A lot of research has gone into the development of Pacemakers and other CIEDs, which are compatible with MRimaging.
